Layers and perimeters

<p dir="ltr">3D printers work by laying layer over layer of plastic to create a 3D object. Each new layer must be supported by the one beneath it. If part of your model starts in mid-air and is not supported by anything below, you need to add an additional support structure to ensure a successful print.</p>
<div class="tip-callout">It is worth considering altering the orientation of the model or splitting the model into multiple parts in order to possibly reduce overhangs and consequently the amount of supports generated.</div>
<p dir="ltr">PrusaSlicer can both detect areas that need supports and generate them in these places <strong>automatically</strong>.</p>
<p dir="ltr">You can also set supports manually using:</p>
<ul>
<li dir="ltr"><a href="http://help.prusa3d.com/article/paint-on-supports_168584">Paint on supports</a></li>
<li dir="ltr"><a href="http://help.prusa3d.com/article/modifier-meshes-custom-supports-and-other-magic_114258#custom-supports">Support enforcers and blockers</a></li>
</ul>
<p dir="ltr">Supports can be turned on from the <strong>right panel</strong> or in the <strong>Print settings - Support material - Generate support material</strong>.</p>
<p dir="ltr">There are 3 different Support styles in PrusaSlicer</p>
<ul>
<li dir="ltr">Grid</li>
<li dir="ltr">Snug</li>
<li dir="ltr"><a href="http://help.prusa3d.com/article/organic-supports_480131">Organic</a></li>
</ul>
<p dir="ltr">When the print finishes, depending on the model geometry and material used, the support structure is often easily removable with bare hands. You can use pliers to get a better grip in otherwise hard-to-reach places. A scalpel or a utility knife can also be used to cleanly remove a piece of support that seems to be stuck to the model.</p>
<div class="warning-callout">Pieces of supports can be surprisingly sharp and are sometimes violently ejected in a random direction after removal. When you encounter hard-to-remove supports, <strong>consider wearing protective glasses</strong> (this sounds stupid until you get hit in the eye for the first time).</div>
<h3 dir="ltr">Supports everywhere</h3>
<p dir="ltr">Supports can grow from both the print bed and any model surface when necessary. </p>
<p dir="ltr">This ensures that every overhang and part starting mid-air will get supported. However, small imperfections may appear on the surface where supports started growing from.</p>
<h3 dir="ltr">Supports from build plate only</h3>
<p>Creates only supports that have their base at the print bed.</p>

<p style="text-align: center;"><em>Supports from build plate only (left), supports everywhere (right)</em></p>
<h3 dir="ltr">For support enforcers only</h3>
<p dir="ltr">Automatic support generation is enabled only for areas marked with a support enforcer. This option is essentially a shortcut that turns <strong>Print settings - Support material - Generate support material</strong> on, but <strong>Print settings - Support material - Auto-generated supports</strong> off.</p>
<h3 dir="ltr">Supports on/off for individual models</h3>
<p dir="ltr">It’s possible to print multiple objects at once each with its own support settings. By default, all models are affected by the global settings. You can overwrite them by <strong>right-clicking</strong> on a model in the 3D view and selecting <strong>Support material</strong>. Alternatively, you can right-click on the editing icon in the Object list.</p>
<p dir="ltr">A new window will appear in the right panel called <strong>Object settings to modify - Support material</strong>. Changing these settings will affect only the relevant object and its instances. You can remove the settings overwrite by clicking on the red cross icon. When you do so, the global settings will once again be applied.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-300x149.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-600x299.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-768x383.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-800x399.png 800w" alt="" width="495" height="247" loading="lazy" /></p>
<h3 dir="ltr">Support enforcer/blocker</h3>
<p dir="ltr">The automatic supports can sometimes appear in hard-to-reach places, resulting in a tedious removal of support structures. If you think such a part of the model could be printed without supports, but neither the <strong>Overhang threshold</strong> setting nor selecting <strong>Supports on built plate only</strong> helped, you can adjust supports manually.</p>
<div class="tip-callout">Starting with PrusaSlicer 2.3, you can also use <a href="http://help.prusa3d.com/article/paint-on-supports_168584">Paint on supports</a>.</div>
<p dir="ltr"><strong>Right-click</strong> on a model and choose either a <strong>Support blocker or Support enforcer</strong>.</p>
<p dir="ltr"><span style="color: #2dc26b;"><strong>Simple mode</strong></span> - Enforcers/blockers are always box-shaped</p>
<p dir="ltr"><span style="color: #f1c40f;"><strong>Advanced mode</strong></span> - Box/Cylinder/Sphere/Slab shapes</p>
<p dir="ltr"><span style="color: #ba372a;"><strong>Expert mode</strong></span> - Option to load external geometry as a blocker/enforcer</p>
<p dir="ltr">Support blockers and enforcers can be manipulated with the familiar Move, Rotate, and Scale tools. You can also quickly duplicate them with copy&amp;paste.</p>
<h3 dir="ltr">Support blocker</h3>
<p dir="ltr">Support blockers are useful when you’re generally happy with the automatic supports and you simply want to remove some of them. Focus on placing blockers where the supports meet the object, the rest of the support structure below will be removed automatically.</p>
<h3 dir="ltr">Support enforcers</h3>
<p dir="ltr">Support enforcers are great in situations, where only a few parts of the object need to be supported, but the automatic algorithm places supports all over the model. In this situation, don’t forget to switch the support mode to For support enforcers only. </p>
<p dir="ltr">It’s less common, but you can also use support enforcers with the automatic generation on.</p>
<p dir="ltr">Another interesting use of support enforcers is to split long bridges into smaller ones by placing a support in the middle of the bridge. You can repeat this process and print shorter, near-perfect bridges while still making the supports easy to remove.</p>
<div class="note-callout">Some options will only appear when <a href="http://help.prusa3d.com/article/simple-advanced-expert-modes_1765">Expert mode</a> is selected.</div>
<h3 dir="ltr"><strong>Generate support material</strong></h3>
<p dir="ltr">Supports are disabled unless a model has an overwrite for this setting</p>
<h3 dir="ltr"><strong>Auto-generated supports</strong></h3>
<p dir="ltr">When off, the overhang detection is off. Only support enforcers generate supports.</p>
<h3 dir="ltr"><strong>Overhang threshold</strong></h3>
<p dir="ltr">The Overhang threshold value represents the most horizontal slope (measured from the horizontal plane) that you can print without support material (90=vertical).</p>
<p dir="ltr">Changing this value is a quick way to adjust the amount of generated supports.</p>
<p dir="ltr">The lower the value, the less support will be generated.</p>

<h3 dir="ltr"><strong>Enforce support for the first</strong></h3>
<p dir="ltr">Generate support material for the specified number of layers counting from the bottom, regardless of whether normal support material is enabled or not and regardless of any angle threshold. This is useful for getting more adhesion of objects having a very thin or poor footprint on the build plate.</p>

<h3 dir="ltr"><strong>Raft layers</strong></h3>
<p dir="ltr">The object will be raised by this number of layers and support material will be generated under it. When the print finishes, you can grab the raft and peel it away from the part.</p>
<h3 dir="ltr">Raft contact Z distance</h3>
<p>The vertical distance between the raft and the object. Ignored for soluble interfaces.</p>
<h3>Raft expansion</h3>
<p>Expansion of the raft in the XY plane for better stability.</p>
<h3>Style</h3>
<p>Style and shape of supports. The default <strong>Grid</strong> supports have a very well-defined minimum area, making them very stable. However, they tend to leak out of regions they support along the walls of the object. The <strong>Snug</strong> supports maintain the shape of the overhang, so they do not leak to the walls. The trade-off is the possibility of lower stability of tall and thin support pillars.</p>

<p style="text-align: center;"><em>Grid supports (left), Snug supports (right)</em></p>
<p><a href="https://help.prusa3d.com/article/organic-supports_480131"><strong>Organic supports</strong></a> offer a completely different approach to supporting overhanging areas. Branches of support structures grow from the sides and automatically get denser beneath parts that need the support. The Organic supports are easily removable, do not scar the surface, and are fast and cheap to print.</p>
<figure class="image" style="text-align: center;"><img decoding="async" title="Support material" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/07/30cd916294dd7ac737ac7c09e1edfbb9.jpg" alt="" width="2011" height="1119" loading="lazy" /><figcaption>Grid supports (left), Organic supports (right)</figcaption></figure>
<h3 dir="ltr"><strong>Top contact Z distance</strong></h3>
<p dir="ltr">The vertical distance between the object and the support material interface.</p>
<p dir="ltr">Setting this to 0 will prevent PrusaSlicer from using bridge flow and speed for the first object layer.</p>
<p dir="ltr">Values between 50-75% of the layer height seem to work well.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-300x191.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-600x381.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-768x488.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-800x508.jpg 800w" alt="" /></p>
<h3 dir="ltr">Bottom contact Z distance</h3>
<p>Similar to Top contact Z distance, but affecting the gap at the bottom of the support tower (when supports start on top of a model and not on the build plate).</p>
<h3 dir="ltr"><strong>Pattern</strong></h3>
<p dir="ltr">Rectilinear - default, usually the easiest to remove</p>
<p dir="ltr">Rectilinear grid - sturdier and less prone to breaking during printing compared to rectilinear infill, harder to remove</p>
<p dir="ltr">Honeycomb - sturdy, somewhat difficult to remove</p>
<h3 dir="ltr"><strong>With sheath around the support</strong></h3>
<p dir="ltr">Creates a single perimeter around the supports, which makes them sturdier, but more difficult to remove.</p>
<h3 dir="ltr"><strong>Pattern spacing</strong></h3>
<p dir="ltr">Spacing between support material lines. Increase to make support removal easier. Support interface layers bridge over support material lines, if you increase this value too much, these bridges will start to sag and have an imperfect connection with the model.</p>
<p dir="ltr">The pattern spacing also sets the internal resolution of PrusaSlicer's supports grid. If you're using Paint-on supports or Support enforcers and you're unable to force supports exactly where you want them to be, try lowering the pattern spacing to get more resolution.</p>
<h3 dir="ltr"><strong>Pattern angle</strong></h3>
<p dir="ltr">Rotates infill pattern angle on the horizontal plane.</p>
<h3 dir="ltr">Closing radius</h3>
<p>For Snug supports only. Gaps smaller than the closing radius will be filled in.</p>
<h3 dir="ltr"><strong>Top interface layers</strong></h3>
<p dir="ltr">Interface layers form a more uniform surface between the object and the support material. These are preferably set to a much denser pattern than the non-interface layers so that you can both maximize the surface area of the support in contact with the model to prevent sagging while minimizing print time and material used with a bigger non-interface pattern spacing.</p>
<h3 dir="ltr">Bottom interface layers</h3>
<p>Similar as Top interface layers, but affecting the number of interface layers at the bottom of the support tower (when supports start on top of a model and not on the build plate).</p>
<h3 dir="ltr"><strong>Interface pattern spacing</strong></h3>
<p dir="ltr">Spacing between interface lines. Set to 0 to get a solid interface.</p>
<h3 dir="ltr"><strong>Interface loops</strong></h3>
<p dir="ltr">When enabled, the top layer of supports is covered with loops - continuous polylines.</p>
<h3 dir="ltr"><strong>Support on build plate only</strong></h3>
<p dir="ltr">Supports can start only on the print bed. Enabling this option is a really quick way to get rid of excess supports mostly on organic shapes. Make sure to check the preview and verify that all parts are either supported or at an overhang angle manageable by the printer.</p>

<p dir="ltr" style="text-align: center;"><em>Supports everywhere (left) vs Supports on build plate only (right)</em></p>
<h3 dir="ltr"><strong>XY separation between an object and its support</strong></h3>
<p dir="ltr">Sets the width of a gap between the model and supports. Bigger XY separation decreases the contact area of supports but makes them easier to remove and less prone to fusing to the model.</p>
<p dir="ltr">If expressed as a percentage (for example 150%) it will be calculated over the external perimeter width.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-300x151.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-600x301.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-768x386.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-800x402.jpg 800w" alt="" /></p>
<h3 dir="ltr"><strong>Don’t support bridges</strong></h3>
<p dir="ltr">Prevents support material from being generated under bridged areas.</p>
<h3 dir="ltr"><strong>Synchronize with object layers</strong></h3>
<p dir="ltr">Supports will be printed at equal layer heights as the model itself. This is useful with multi-material printers, where the extruder switch is expensive.</p>
<p>Synchronize with object layers can only be enabled with soluble supports (contact Z distance 0). </p>
<p>Not synchronizing with object layers allows the support layers to grow faster than the object layers (if not excessively slowed down by the cooling logic) and independent layer height also allows PrusaSlicer to follow the gap between the object and the support top surface precisely. We may consider this to be configurable even for non-soluble supports in the future.</p>
<p> </p>


Support material

<p dir="ltr">The main purpose of infill is to provide internal support for top layers, which would otherwise have to bridge over empty space. Infill also affects the speed of printing, structural strength, filament consumption, and even the look of the printed object.</p>
<div class="note-callout">Some options will only appear when <a href="http://help.prusa3d.com/article/simple-advanced-expert-modes_1765">Expert mode</a> is selected.</div>
<h3>Fill density</h3>
<p>Most models can be printed with 10-15% infill. If the top of the model closes gradually, it can be printed hollow (0% infill), though we generally do not recommend it. If you need the model to be heavier, want more compression resistance or higher stiffness, you can increase the infill. You'll rarely need infill higher than 30%. Finally, you can print the model with 100% infill and the infill pattern will be forced to rectilinear. Keep in mind that 100% infill can have a negative impact on the look of the printed object.</p>
<div class="tip-callout"><strong>Increasing model strength</strong><br />The strength of a model is mostly defined by the number of <strong>perimeters (not infill</strong>). If you want to have a stronger print, increase the number of perimeters. That said, infill does help with compression resistance.</div>
<h3>Fill pattern</h3>
<p>PrusaSlicer offers many infill patterns to choose from - check the dedicated <a href="http://help.prusa3d.com/article/infill-patterns_177130"><strong>Infill pattern documentation page</a></strong>.</p>
<h3>Length of the infill anchor</h3>
<p>The infill is usually <strong>connected to the perimeters</strong> with a so-called anchor, which is a <strong>short line</strong> of another (inner) perimeter that turns into an infill line. This makes the infill sturdier and is required by some materials (namely PETG) to stabilize the extrusion flow at the start of an infill line.</p>
<p>The length of the infill anchor value sets how many millimeters of this anchor will connect the infill and the perimeters. If you set this value to 0, the infill will be printed independently on the perimeters. Set a higher value to print the anchor that will continue as the infill itself.</p>
<p>If expressed as a percentage (15%) it will be calculated over the infill extrusion width.</p>

<h3>Maximum length of the infill anchor</h3>
<p>This value sets the maximum length of the infill anchor connecting the infill with perimeters.</p>
<p>Set this parameter to 0 to disable anchoring completely.</p>
<h3>Top fill pattern</h3>
<p>You can pick a custom infill pattern that only affects the top visible layer, not adjacent solid layers below. </p>
<h3>Bottom fill pattern</h3>
<p>You can pick a custom infill pattern that only affects the bottom visible layer, not adjacent solid layers above.</p>
<h3>Combine infill every X layers</h3>
<p>Different layer heights will be used for infill and for perimeters in order to speed up the print without sacrificing the print quality.<br />Example: Combine infill every 3 layers, layer height 0.1 mm, infill will be printed at 0.3 mm layer height.</p>
<div class="note-callout">The maximum layer height is limited by your nozzle diameter. If you try to combine infill every 1+ layers with 0.4 mm nozzle and 0.3 mm layer height, no change will actually happen because you cannot print layers bigger than (about) 0.32mm (80% of nozzle diameter).</div>

<div style="text-align: center;"><em>Infill (grey) printed at double the layer height of perimeters (orange)</em></div>
<p style="text-align: center;"> </p>
<h3>Solid Infill every X layers</h3>
<p>This feature allows you to force a solid layer after every given number of layers. This can be useful to increase the strength of the printed part, however other options, such as increasing the number of perimeters or infill percentage are preferred. Another application would be to create separate internal cells in order to increase thermal insulation.</p>
<p><strong>Set to 0 to disable.</strong></p>
<h3>Fill angle</h3>
<p>Default angle for infill orientation. Cross-hatching will be applied to some infill patterns.</p>
<div class="note-callout"><strong>Bridges</strong> will be printed using the best direction PrusaSlicer can detect, so this setting does not affect them.</div>
<h3>Solid infill threshold area</h3>
<p>Force solid infill for regions having a smaller area than the specified threshold.</p>
<p><strong>Set to 0 to disable.</strong></p>

<p><span>Unlike FDM supports, which are usually lattice or grid-like, SLA supports are <strong>scaffolding tree-like structures with very thin tips</strong>. They’re easy to remove and they leave little to no traces on the printed object’s surface when removed. This also means that an insufficient number of supports can lead to unwanted effects – e.g. heavy objects can detach during the print. Supports go hand in hand with object orientation – by rotating the object to an optimal position, you can minimize the need for supports.</span></p>
<div><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/t_rex_orientation-1.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/t_rex_orientation-1-300x194.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/t_rex_orientation-1-600x388.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/t_rex_orientation-1-768x497.jpg 768w" alt=""></p>
<p>You can get rid of tons of supports if you rotate the object to an optimal position. Teeth on this T-rex head can be printed without supports</p>
</div>
<p>Also, keep in mind that removing the supports can leave tiny marks on the surface, so if your object has certain areas that should be completely flawless (an ornament on a piece of jewelry, face of an action figure), try to keep the supports away from them.</p>
<p>PrusaSlicer 2.0 is fully equipped for automatic tree support generation. How does it work?</p>
<ol>
<li>Select the object that requires supports</li>
<li>Click the SLA support points icon</li>
<li>Choose the support point density and minimal points distance (default values should work fine for a majority of objects)</li>
<li>Click Auto-generate points and wait until the process is finished</li>
<li>Use the Preview mode to inspect whether all “islands” are supported – if not, you can manually adjust the supports.</li>
</ol>

<p style="text-align: center;"><em>SLA Support menu in PrusaSlicer</em></p>
</div>
<p>Another thing that you should consider using is the pad.&nbsp;<strong>The pad</strong>&nbsp;(enabled by default) is a large structure at the base of the print, which serves as the foundation for the supports. While it’s possible to have supports printed directly on the aluminum printing platform, the pad will ensure much better stability.</p>
<div class="note-callout">If you're printing your model solid, it can be quite heavy. Consider <strong><span class="tooltip" data-tooltip="hollowing_117439">hollowing</span></strong> the model or <strong>add more supports, and/or make them thicker,</strong>&nbsp;so they can support the object’s weight.</div>
<h3>Manual support editing</h3>
<p>In some cases, the automatic support generation doesn’t deliver a 100% perfect result – this is normal since imported objects can be infinitely complex. We’re constantly improving our support generation subroutines to prevent these situations from happening. Either way, on certain occasions, supports have to be added manually – this can be done even when there are already auto-generated supports in place.</p>
<p>&nbsp; <img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/automatic_manual_supports.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/automatic_manual_supports-300x115.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/automatic_manual_supports-600x231.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/automatic_manual_supports-768x296.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/automatic_manual_supports-800x308.png 800w" alt=""></p>
<p style="text-align: center;"><em>Comparison of automatically generated supports and manually edited supports</em></p>
<p>Click the <strong>Manual editing</strong> button. Previously generated supports will temporarily disappear to give you a better overview of the model. Use the <strong>left mouse button</strong> to <strong>add new support points</strong>. You can tweak the support thickness in manual editing mode by using the <strong>Head diameter</strong>&nbsp;slider, or you can go to <strong>Print settings – Supports</strong> and modify the following parameters to increase the thickness of supports:</p>
<ul>
<li>Support head front diameter: 0.6 mm</li>
<li>Support head penetration: 0.6 mm</li>
<li>Support pillar diameter: 1.3 mm</li>

<h3>Welcome to PrusaSlicer documentation (PrusaSlicer manual)</h3>
<p>PrusaSlicer (formerly known as Slic3r Prusa Edition or Slic3r PE) is our own in-house developed slicer software based on the open-source project <a href="https://slic3r.org/"><strong>Slic3r</strong></a>. PrusaSlicer is an open-source, feature-rich, frequently updated tool that contains everything you need to export the perfect print files for (not only) your Original Prusa 3D printer.</p>
<p>PrusaSlicer is available for <a href="http://help.prusa3d.com/article/download-prusaslicer_2220">Windows, Mac and Linux</a></p>
<h3>History</h3>
<p>The Slic3r project was born in 2011 within the RepRap community as an effort to provide the growing 3D printing technology under the leadership of&nbsp;<strong>Alessandro Ranellucci</strong> an open-source slicer. Slic3r spread among users quickly. When Josef Prusa was looking for a leading slicing software for Original Prusa printers the choice fell on Slic3r. It was (and still is) an open-source and very powerful software.&nbsp;</p>
<p style="text-align: center;"><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/en/wp-content/uploads/jo_and_allesandro.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-300x170.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-600x341.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-768x436.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/jo_and_allesandro-800x454.png 800w" alt="" width="421" height="239"><em>Jo and Alessandro in 2012 (<a href="https://youtu.be/Tuxg2L7r1oI">video interview</a>)</em></p>
<p>However, as Prusa Research was growing (very, very, very fast), we needed to be more flexible with the slicing software development. We needed to make changes to the software, and the changes had to be done asap. We also needed to add more features. At this point the co-operation with the detached original Slic3r team was unsustainable. The bottom line is that we decided to establish a fork of the original Slic3r project.</p>
<p>Slic3r Prusa Edition was released in November 2016 – <a href="https://blog.prusaprinters.org/introducing-slic3r-prusa-edition_4650/">read more about the launch here</a>. A dedicated team of full-time Slic3r PE developers was established and new functions were being added rapidly. These changes culminated in May 2019, when we released a new version with a major UI overhaul under a new name - <a href="https://blog.prusaprinters.org/prusaslicer-2-release_30008/">PrusaSlicer 2.0</a>.&nbsp;</p>
<p>Why the name change? First of all, the old name was really confusing. Even in our own materials, we often didn’t include the “PE” suffix, and the community used Slic3r and Slic3r PE pretty much interchangeably. New users could mistakingly download Slic3r and wonder why it looks different from the screenshots in the 3D Printing Handbook and why it’s not configured for their Prusa printer. Speaking about the original Slic3r: with each update, Slic3r PE was moving further and further away from its original code. We’ve rewritten all of the Perl source code into C++ and especially with the 2.0 update, there were so many differences that it seemed appropriate to make the name more distinct.</p>
<p>Of course, it’s still open-source and you’ll find everything on our <a href="https://github.com/prusa3d/PrusaSlicer">GitHub</a>. <strong>And we’re still proud that our slicer is based on the <a href="https://slic3r.org/">original project written by Alessandro Ranellucci</a>!</strong> Both projects now happily coexist and new features are frequently merged between one and another.</p>


General info

Prusa Connect &amp; PrusaLink

<p>Prusa Connect and PrusaLink are two remote printing solutions developed in-house by Prusa. Its origin is in the management system used in our <a href="https://blog.prusaprinters.org/guinness-world-records-1096-original-prusa-3d-printers-running-at-the-same-time_30677/">record-sized print farm located in Prague HQ.</a></p>
<ul>
<ul>
<li><strong>Prusa Connect</strong> is a cloud service for remote printing available from anywhere.</li>
<li><strong>PrusaLink</strong>* is the client-side running locally on your printer, accessible from local network</li>
</ul>
</ul>
<p><em>*formerly known as Prusa Connect Local</em></p>
<p> </p>
<h2>What is Prusa Connect?</h2>
<p>Prusa Connect (<a href="http://connect.prusa3d.com">connect.prusa3d.com</a>) allows you to control your individual printers or even manage a print farm from anywhere in the world.</p>
<p style="text-align: center;"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/08/9f18d1552ef82ea7ef4960a43a86a17b.png" sizes="(min-width: 1024px) 820px, 100vw" srcset="Prusa Connect and PrusaLink explained" alt="" width="900" height="607" loading="lazy" /></p>
<p style="text-align: center;"><em>Example of Prusa Connect interface (cloud service)</em></p>
<p> </p>
<p>It is available for free to the owners of selected Original Prusa printers (see the list below). You get a free 1 GB of cloud storage for your G-codes and telemetric data. The full list of features and pricing for end customers or businesses will be announced later on.</p>
<p>Furthermore, Prusa Connect is able to monitor the use of each printer individually, providing valuable statistics of your production environment. </p>
<p> </p>
<h2>What is PrusaLink?</h2>
<p>Much like <a href="http://help.prusa3d.com/article/about-octoprint_1790">Octoprint</a>, this remote printer-management system runs locally on your Original Prusa printer.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/01/12af6bd49830e088.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="PrusaLink and Prusa Connect explained" alt="" width="1451" height="800" loading="lazy" /></p>
<p style="text-align: center;"><em>Example of PrusaLink interface (local network)</em></p>
<p> </p>
<p>Its main goal is to provide communication between your printer and the Prusa Connect cloud. The secondary function is to provide a web interface, which can be used on your local (home) network only. Simply paste the printer's IP address into your web browser to access it. Using PrusaLink alone you can monitor your printer, upload G-codes, start or cancel a print. </p>
<p> </p>
<h2>How to install and configure PrusaLink and Prusa Connect?</h2>
<p>To use the Prusa Connect, you have to first set up the PrusaLink on your printer. The guides below will take you to step by step through the entire process.</p>

<h3>Next-gen Original Prusa printers</h3>
<p>Such as the<strong> MK4, MK3.9, MK3.5, XL, MINI/+, SL1/SL1S </strong> as well as the other upcoming models have the PrusaLink built-in. You can connect the printer either using Wi-Fi or a wired LAN (Ethernet) network. Note that on MINI/+, you have to first <a href="http://help.prusa3d.com/guide/installing-wi-fi-and-prusalink-mini-_316781">install the Wi-Fi module</a> to use the wireless functionality.</p>

<p> </p>
<h3>Original Prusa i3 MK3/S/+ or MK2.5/S</h3>
<p>In this case, the PrusaLink name also refers to the required hardware solution of a Raspberry Pi (RPi). These printers don't have enough performance, therefore additional hardware is required. PrusaLink is a replacement for the discontinued <a href="http://help.prusa3d.com/article/prusaprint-rpi-zero-and-octoprint_2180">PrusaPrint solution</a> (Octoprint and the RPi Zero W).</p>
<h4>Which Raspberry Pi should I get for my i3 (MK3/S/+ or MK2.5/S)?</h4>
<p>For your MK3/S/+, you need to get a Raspberry Pi (RPi) to make the PrusaLink and Prusa Connect work. The supported RPi boards are listed below and if you are about to purchase a new one, it is highly recommended to seek the latest generation, as the older ones might be slower.</p>
<p>On MK3/S/+, you can attach the RPi Zero <a href="http://help.prusa3d.com/guide/prusalink-and-prusa-connect-setup-mk3-s-_221744">directly onto the printer’s mainboard</a> or use the <a href="http://help.prusa3d.com/guide/prusalink-prusa-connect-with-rpi-3-4-usb-mk2-5-s-mk3-s-_469341">USB connection</a>.<br />On MK2.5/S, you have to use the <a href="http://help.prusa3d.com/guide/prusalink-prusa-connect-with-rpi-3-4-usb-mk2-5-s-mk3-s-_469341">USB connection</a> to the RPi. Then, the PrusaLink and PrusaConnect setup is fairly similar to the MK3/S/+.</p>
<p>Since the RPi doesn't have internal storage, you need to get a MicroSD card. Recommended SD card: Micro SD, SDHC standard, Class 10, 8GB or more. Preferably, choose a name-brand card known to work with RPi. Do backups regularly as even a name-brand card doesn’t guarantee you won’t lose your data. </p>

Prusa Connect and PrusaLink explained

<p><strong>Standalone PrusaSlicer G-code Viewer</strong>&nbsp;is a lightweight application, which you can use to quickly preview G-codes from all popular slicers. Its behavior is identical to the preview in PrusaSlicer (the same code is used), however, you can load an external G-code file.</p>
<h3>Supported slicers</h3>
<p>We currently parse, and up to some level interpret, G-code from:</p>
<ul>
<li>PrusaSlicer</li>
<li>Slic3r and Slic3rPE</li>
<li>CURA</li>
<li>ideaMaker</li>
<li>Simplify3D</li>
<li>Craftware</li>
<li>KISSSlicer</li>
</ul>
<p><img decoding="async" loading="lazy" src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/gcode_viewer.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/gcode_viewer-600x395.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/gcode_viewer-800x526.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/gcode_viewer-300x197.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/gcode_viewer-768x505.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/gcode_viewer-1536x1011.jpg 1536w" alt="" width="1787" height="1176"></p>
<p>PrusaSlicer Standalone G-code Viewer tries hard to estimate the extrusion widths, layer heights, extrusion types, types of moves, layers, etc. from the G-code generated by various slicers. The G-code itself does not contain all the information mentioned above, thus the G-code is usually augmented with slicer specific comments. We try to get as much data as possible, but some parts might still get marked as unknown.</p>
<p>PrusaSlicer version 2.3 and newer augments the G-code with comments ";TYPE:", ";HEIGHT:", ";LAYER_CHANGE", ";COLOR_CHANGE", ";PAUSE_PRINT" and ";CUSTOM_GCODE". G-code generated by older PrusaSlicer which does not contain these new annotations will still be displayed, but the extrusion widths or extrusion types may not be shown reliably.</p>
<p>G-code generated with other slicers will most likely still load correctly, but some features, such as the print time analysis by feature might be unavailable.</p>
<h3>Associate with .gcode file extension</h3>
<p>If you associate the .gcode file extension with the G-code viewer, you'll be able to launch it simply by opening the file (double-clicking on it or pressing Enter). You can do so by enabling <strong>Configuration - Preferences - Associate .gcode files to PrusaSlicer G-code Viewer</strong>.</p>
<p>Alternatively, you associate the file extension using your operating system tools.</p>
<h4>Windows</h4>
<ol>
<li>Right-click any G-code file</li>
<li>Select <strong>Open with - Choose default program...</strong> -&nbsp;<strong>PrusaSlicer G-code Viewer</strong></li>
<li>Click <strong>More</strong> at the bottom</li>
<li>Tick <strong>Always use this app</strong></li>
</ol>
<h4>macOS</h4>
<ol>
<li>Select any G-code file in the Finder and choose <strong>File &gt; Get Info</strong></li>
<li>In the Open With section, select <strong>PrusaSlicer G-code Viewer</strong></li>
<li>Click <strong>Change All</strong> and confirm</li>
</ol>
<h4>Ubuntu</h4>
<ol>
<li>Select any G-code file</li>
<li>Right-click the file and select <strong>Properties</strong></li>
<li>Select the <strong>Open With</strong> tab</li>
<li>Select <strong>PrusaSlicer G-code Viewer</strong> and click <strong>Set as default</strong>.</li>
</ol>
<p>The process is similar on other Linux distributions.</p>
<h3>Features</h3>
<p>The stand-alone G-Code Viewer shows names of used Printer/Print settings/Filament.</p>
<p>Once the final G-code is available after slicing, a new horizontal slider shows up, limiting visualization of extrusions and travel by time thus allowing simulation of the print in time. By default the new horizontal slider limits visualization of the last layer selected by the vertical toolbar. Alternatively the horizontal slider limits the extrusions in all layers selected by the vertical slider. In the first case, if the horizontal slider limits visibility of the top layer, then the other layers below are rendered in a gray color. We borrowed this visualization strategy from the Craftware user interface as Cura did.</p>
<p>The legend newly shows the print time and the print time fraction per feature (perimeter, infill etc.), and the legend labels serve as buttons to show / hide the particular extrusion time. The print time estimate is available in both the G-code preview after slicing and in the stand-alone G-code viewer.</p>
<h4>Multiple instances</h4>
<p>One can start as many PrusaSlicer G-code Viewers as he wishes either by opening a G-code from the "File-&gt;G-code preview" menu, by starting the G-code viewer application, or by double-clicking on a G-code file in a File Explorer/Finder.</p>
<h3>How it works</h3>
<p>From the technical point of view, the stand-alone G-code viewer is a PrusaSlicer in disguise. The stand-alone G-code viewer is started as a new PrusaSlicer process. The way how the G-code viewer process is started is platform specific:</p>
<h4><strong>Windows</strong></h4>
<p>The PrusaSlicer.dll contains all the code while the prusa-slicer.exe, prusa-slicer-console.exe and the new prusa-gcodeviewer.exe wrappers just load PrusaSlicer.dll with the proper parameters.</p>
<h4><strong>OSX</strong></h4>
<p>The application distribution format supports a single binary, which in our case is PrusaSlicer.app/Contents/MacOS/PrusaSlicer. For command-line usage, this binary may be symlinked to prusa-gocdeviewer to start in a G-code viewer mode. Starting new instances of PrusaSlicer does not quite fit the OSX system, as the Finder only expects a single instance of a GUI application to be running. Thus when drag &amp; dropping onto a dock icon of PrusaSlicer resp. G-code viewer, the file is sent to the first instance of PrusaSlicer resp. G-code viewer.</p>
<h4><strong>Linux</strong></h4>
<p>We support two binary distributions: AppImage and .tar.bz2. The .tar.bz2 format contains a new prusa-gcodeviewer starter script, while the AppImage may be symlinked to prusa-gcodeviewer to start the G-code viewer. The AppImage works by mounting the zipped filesystem image embedded inside the AppImage file and starting the application from there. It is not recommended to start prusa-gcodeviewer from an already mounted AppImage, as the AppImage will be unmounted when the PrusaSlicer that mounted it closes. When the user starts a G-code viewer from an AppImage PrusaSlicer application, another AppImage is mounted by the G-code viewer, which means the PrusaSlicer binary is being loaded into RAM the second time. Therefore if one is low on RAM, it is recommended to use the .tar.bz2 distribution instead of the AppImage until the AppImage is improved to support multiple processes running from a single mounted AppImage.</p>

<p dir="ltr">In some cases, you might want to cut a model into multiple pieces before printing:</p>
<ul>
<li dir="ltr" role="presentation">the model is too big to be printed in one piece</li>
<li dir="ltr" role="presentation">you only want to print a part of a model</li>
<li dir="ltr" role="presentation">a part of the model needs a different print orientation for added strength</li>
<li dir="ltr" role="presentation">printing the model in one piece would require a needlessly large amount of support material</li>
</ul>
<p>PrusaSlicer provides an advanced cutting function:</p>
<ul>
<li>Cut models at any angle</li>
<li>Select which parts to separate and which to keep connected</li>
<li>Generate connectors and dowel pins for easy assembly</li>
</ul>
<p dir="ltr">Select the object and press the <span class="key">C</span> key or pick the <strong>Cut tool</strong> from the left toolbar. A 3D gizmo and a context menu will appear. Using the gizmo, you can drag the cutting plane to your desired position. To set the cutting plane position, you can also enter an exact value [mm] in the context menu. To change the rotation of the cutting plane, use the arrows on top of the gizmo.</p>

<p dir="ltr">You can also hold down the <span class="key">Shift</span> key and click on two points on the screen to quickly define a cutting plane. The cutting plane will be perpendicular to the current view.</p>
<p dir="ltr"><video autoplay="autoplay" loop="loop" muted="" controls="controls" width="925" height="auto"><source src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/01/prusa-slicer_7DRpujRGfr-1.mp4" type="video/mp4" /></video>  </p>
<p dir="ltr">For both the top and bottom part, you have the option to:</p>
<ul>
<li dir="ltr"><strong>Keep </strong>- toggles whether the part should remain in the 3D view or be deleted after the cut</li>
<li dir="ltr"><strong>Place on cut</strong> - rotates the parts so that the cut area aligns perfectly with the heatbed</li>
<li dir="ltr"><strong>Flip</strong> - rotates the model upside down after cutting</li>
</ul>

<h3 dir="ltr">Select which parts to separate and which to keep connected</h3>
<p dir="ltr">If the cutting plane intersects the model in several different regions, you can select which parts to cut and which to keep connected by right-clicking on them.</p>

<h3 dir="ltr">Adding connectors and dowel pins</h3>
<p dir="ltr">We understand how important it is to assemble the final parts together with an emphasis on precision and simplicity. That’s why we added an option to define various types of connectors. You can control the depth, size, and tolerances of each connector and the negative hole.</p>
<p dir="ltr">The <strong>Plug</strong> type will add extra geometry to one side of the cut and subtract it from the other side. The <strong>Dowel</strong> type will subtract the pin from both sides and generate and extra object to print as the connector.</p>

Sample G-codes

<h3 dir="ltr">Model import</h3>
<p dir="ltr">First, you have to import your model. You can either <strong>drag and drop</strong> it directly to the PrusaSlicer window, use the <strong>Add button</strong> in the top toolbar or choose <strong>File - Import</strong>.</p>
<p dir="ltr">Supported 3D formats are STL, STEP, 3MF, OBJ, and AMF.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://lh5.googleusercontent.com/YX3xyJG4ArooSiafY0RO5jOmiVN2lceTx3llzIaBIBDAWSMvhVSnqFVpY0Ci5_ZtncNRKYUZJAOhb98M0_hUE6wxJL8PhpQL362SE2g9Lizofu2SRoTuHA1rwj5IrjEBUorPvV6j" width="500" height="281" loading="lazy" /></p>
<h3 dir="ltr">Model orientation</h3>
<p dir="ltr">It’s possible that your model may be oriented incorrectly after import. If that’s the case you can use to <strong>Rotate tool</strong> <span class="key">R</span> to manually adjust to the object’s orientation. When you pick a rotation axis, you can use the short guidelines to rotate by 5-degree increments or the long guidelines, which snap to 45-degree increments.</p>
<p dir="ltr">Alternatively, you can use the <span class="tooltip" data-tooltip="place-on-face_124588">Place on Face</span> tool. When you select it, several white planes will appear on your model. Clicking on the white plane will align it with the virtual print bed.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://lh3.googleusercontent.com/zs7JvVGbNSZNoP_bSWx9Ux5s-2Qdjl7aGG7_lnhTOBNDoFxBHh772qyUWSNHSLADfKSVbNSE7O0Jseg3CbyM2Jt91U3Zj7zqOJqSN7RrENnsBKY99YeHYLehPI1pGUqXwPxzTd-I" width="602" height="339" loading="lazy" /></p>
<p> </p>
<h3 dir="ltr">Selecting printer</h3>
<p dir="ltr">If you only selected one printer and nozzle size in the <a href="http://help.prusa3d.com/article/configuration-wizard_1754">Configuration Wizard</a>, you already have the correct printer selected. If you chose to import multiple printer profiles, select the one you wish to use from the drop-down menu in the right panel.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/printer_select.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/printer_select-300x131.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/printer_select-600x262.png 600w" alt="" width="490" height="214" loading="lazy" /></p>
<h3 dir="ltr">Selecting material</h3>
<p dir="ltr">Different materials require different print temperatures, print speed, cooling, and a variety of other settings. Luckily, PrusaSlicer comes with presets for many different materials, so you just have to select one from the drop-down menu in the right panel.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/filament_selection.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/filament_selection-176x300.png 176w, https://cdn.help.prusa3d.com/wp-content/uploads/filament_selection-235x400.png 235w, https://cdn.help.prusa3d.com/wp-content/uploads/filament_selection-352x600.png 352w" alt="" width="269" height="458" loading="lazy" /></p>
<h3 dir="ltr">Selecting a print profile/layer height</h3>
<p dir="ltr">By adjusting the height of the individual printed layers you can balance the print quality and the print time. PrusaSlicer has various print profiles to select from. To start we suggest using 0.15 or 0.2 mm layers as they offer very good print quality at reasonable print times.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/print_settings.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/print_settings-300x183.png 300w" alt="" width="268" height="164" loading="lazy" /></p>
<h3 dir="ltr">Supports</h3>
<p dir="ltr">Because each layer rests on top of the previous one, it may be necessary to print a support structure underneath parts, that would otherwise be printed in mid-air. Additionally, it’s difficult for the printer to reproduce very steep overhangs. PrusaSlicer can detect where to place supports and generate them automatically. To turn supports on pick either Supports: Everywhere or Supports: On build plate only from the drop-down menu in the right panel.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/supports.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/supports-300x92.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/supports-600x184.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/supports-768x235.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/supports-800x245.jpg 800w" alt="" /></p>
<p dir="ltr">A model that needs supports (left), a model with generated supports (right)</p>
<h3 dir="ltr">Infill</h3>
<p dir="ltr">Objects are typically not printed solid, but not hollow either. A sparse infill pattern is used to fill the inside of the model. The main purpose of the infill is to provide an internal support structure for top layers, as well as to improve the mechanical properties of the print. On the other hand, we usually want to get away with as little infill as possible to reduce both print times and material consumption.<br />The amount of infill can be adjusted in the right panel. Generally, values around 15% work well.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/infill.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/infill-300x204.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/infill-590x400.png 590w, https://cdn.help.prusa3d.com/wp-content/uploads/infill-768x521.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/infill-800x543.png 800w" alt="" /></p>
<h3 dir="ltr">Brim</h3>
<p dir="ltr">A brim is used to increase adhesion to the print bed and decrease the possibility of warping. This is done by printing extra outlines of the first layer and it’s especially useful when the footprint of the first layer is very small. You can turn it on with a checkbox in the right panel. When the print is finished, it’s usually very easy to remove the brim by hand.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/brim.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/brim-300x180.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/brim-600x359.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/brim-768x460.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/brim-800x479.png 800w" alt="" /></p>
<h3 dir="ltr">Previewing G-code before print</h3>
<p dir="ltr">It’s a good practice to always preview the G-code before printing it. When you click the Slice now button, you’ll be automatically switched to the preview mode. Alternatively, you can use the switch between 3D view and preview mode in the lower-left corner or press the TAB key. Using the slider on the right, you can adjust the preview and inspect individual layers. Check the overall shape of the model and make sure it matches the 3D object. Watch out for parts, that would start printing in mid-air, if you notice any, it’s necessary to turn on support generation. If everything looks alright, you can proceed and select Export G-code.</p>
<h3 dir="ltr">Exporting the G-code</h3>
<p>PrusaSlicer automatically detects if you insert an SD card, USB flash drive, or other removable media.</p>
<p>When detected, a new Export to SD/USB drive button will appear next to the Export G-code button (bottom right corner). Clicking it will open the file save dialog with the path initialized to the SD card or USB flash drive.</p>
<p>If multiple SD cards or USB flash drives are detected, the file dialog is opened at the last visited removable media.<br />Once a G-code is exported to a removable media, an Eject button is shown next to the Export G-code button, which will safely disconnect your device.</p>

First print with PrusaSlicer

<p>By default, PrusaSlicer places the bottom-most point of each object on the build plate.</p>
<p>In the vast majority of cases, this saves the user time and prevents possible failed prints, where the model would be accidentally slightly lifted above the print bed. However, in some cases, you might want to lift an object above the print bed on purpose. For example, you might want to add a logo or text on top of another object.</p>
<p>The way to do it currently is to use a&nbsp;<strong>multi-part object</strong>. Only the bottom-most part of a multi-part object will be placed on the build plate. Other parts can be lifted from the build plate freely.</p>
<h3>Load the "levitating" object as a part</h3>
<ol>
<li><strong>Right-click</strong> an existing object in the 3D View</li>
<li>Select <strong>Add part - Load object..</strong> (or select any of the basic primitives from the list)</li>
<li>Select the <a href="https://help.prusa3d.com/en/article/move-rotate-scale-tools_1914"><strong>Move</strong> <strong>tool</strong></a> from the left menu</li>
<li>Move the part wherever you want it (or use the <a href="http://help.prusa3d.com/article/object-manipulation-panel_1757">Object manipulation panel</a> to enter precise values)</li>
</ol>

<h3>Merge multiple objects</h3>
<p>You can also create a multi-part object by merging multiple objects together</p>
<ol>
<li>Select multiple objects (Use box selection or Ctrl+left mouse button click to add an object to current selection)</li>
<li><strong>Right-click</strong> any of the models</li>
<li>Select&nbsp;<strong>Merge</strong></li>
<li>Select individual part using the Object list</li>
<li>Select the <strong><a href="http://help.prusa3d.com/article/move-rotate-scale-tools_1914">Move tool</a></strong> from the left menu</li>
<li>Move the part wherever you want it (or use the <a href="http://help.prusa3d.com/article/object-manipulation-panel_1757">Object manipulation panel</a> to enter precise values)</li>
</ol>
<h4>Selecting individual parts</h4>
<p>When you click on a multi-part object in the 3D view, all parts will be selected. Use the <a href="http://help.prusa3d.com/article/object-list_1758">Object list</a> in the right panel to select individual parts.</p>

<h3>Why don't we simply allow lifting objects up?</h3>
<p>Contrary to other slicers, PrusaSlicer slices each object independently and it also builds supports for each object independently. This approach is beneficial in many ways, it allows us to do tricks like variable layer height, support stepping independently per object or reslicing only part of the scene when a parameter changes to save time. On the other hand, it also means that objects, and more importantly, supports from two separate objects can collide. Placing one object on top of another and enabling supports would counterintuitively build supports through the bottom object, which would be difficult to see in the preview and ruin the print. Indeed, intersecting supports for objects placed close together is relatively frequently reported as a bug even now.</p>
<p>In addition, the assumption "objects are not floating" is present in many places of the codebase, and there is no simple way to simply allow lifting objects up without breaking many of the existing features.</p>
<p>To summarize, in order to enable this in the future, we will also have to implement:</p>
<ol>
<li>Collision detection on the plater. We already have the infrastructure in PrusaSlicer for that.</li>
<li>Collision of supports from different objects.</li>
</ol>
<p>With that, the user will get meaningful feedback if the print is not printable (floating in mid-air or having overlapping extrusions) Implementing all of this will be fairly difficult. With some more requested tasks from the community having a higher priority for us, we have no estimated deadline for implementing this.</p>


How to lift object from the print bed

<p>In this guide, we'll cover how to import profiles in PrusaSlicer that are not included with the software, and how to export your custom PrusaSlicer profiles. <a href="http://help.prusa3d.com/article/profiles-for-3rd-party-printers_246178">Some 3rd party vendor profiles are already included with PrusaSlicer</a> (e.g. Lulzbot or Creality printers).</p>
<div class="note-callout">A profile is a combination of print settings, filament settings, and printer settings. A profile, or a bundle, is saved in .ini format. </div>
<h3>How to import custom profiles</h3>

How to import and export custom profiles in PrusaSlicer

<p>The Arachne generator produces perimeter loops and gap fills with varying extrusion width. Simply put, it automatically makes perimeters wider or thinner as needed.&nbsp;</p>
<div class="note-callout">For years, the strategy PrusaSlicer used when generating perimeters was to offset the contour of the object with an extrusion line of constant width. This caused issues in various cases, especially when printing thin walls, text, or logos. The developers of Cura implemented a new strategy named Arachne based on the paper <a></a>. We ported the feature from Cura. We want to express our thanks to the Ultimaker Cura team led by Jaime van Kessel, for implementing this feature and for keeping Cura open-source.</div>

&nbsp;</p>
<p>The new approach produces nicer-looking prints with fewer artifacts. There is a significant reduction in gap fill, small extrusions used to fill gaps between perimeters, which also results in a reduction of print time.</p>
<p>One field where the Arachne perimeter generator really shows its power is when printing texts or small logos. Drawing fonts with constant line width is obviously quite difficult. The new perimeter generator doesn’t have this limitation and produces much cleaner texts even at a smaller scale.&nbsp;<strong><img decoding="async" loading="lazy" src="https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy-600x364.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy-800x485.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy-300x182.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy-768x465.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy-1536x931.jpg 1536w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy-2048x1241.jpg 2048w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/texts-copy.jpg 1600w" alt="" width="2017" height="1222"></strong></p>
<p style="text-align: center;"><em>Classic perimeter generator in PrusaSlicer 2.4.2 vs Arachne in PrusaSlicer 2.5</em></p>
<p>We have decided to set the Arachne perimeter generator as the default option. If you want to use the old perimeter generator, you can switch to it in the <strong>Print settings - Layer and perimeters - Perimeter generator settings</strong>.</p>
<p>The Detect Thin walls feature is disabled when the Arachne perimeter generator is selected as it’s not needed since Arachne always tries to adapt the extrusion width to thin lines.&nbsp;</p>
<p>You can adjust the Arachne perimeter generator settings in:<br />
<strong>Print settings - Advanced - Arachne perimeter generator</strong></p>
<h3>Minimum feature size</h3>
<p>Minimum thickness of thin features, expressed in millimeters or as a percentage of the nozzle diameter.</p>
<p>Features thinner than this value will not be printed.</p>
<p>Feature thicker than the minimum will be widened to the minimum perimeter width.</p>
<h3>Minimum perimeter width</h3>
<p>Width of a perimeter that will replace thin features defined by the Minimum feature size.</p>
<h3>Perimeter transition length</h3>
<p>When transitioning between a different number of perimeters as the part becomes thinner, a certain amount of space is allocated to split or join the perimeter segments. This value defines the length of this transition area.</p>
<h3>Perimeter transitioning threshold angle</h3>
<p>An angle at which a transition between even and odd number of perimeters should happen. A wedge shape with an angle greater than this value will not have transitions and no perimeters will be printed in the center to fill the remaining space. Lowering this value reduces the number and length of these center perimeters but may leave gaps or overextrude.</p>
<h3>Perimeter transition filter margin</h3>
<p>This value is used to prevent transitioning back and forth between one extra perimeter and one fewer. It is expressed in millimeters or as a percentage of the nozzle diameter.</p>
<p>Increasing this margin reduces the number of transitions, which reduces the number of extrusion start/stops.</p>
<p>&nbsp;</p>

Arachne perimeter generator

<p>PrusaSlicer supports custom print bed textures and models in both <strong>PNG</strong> and <strong>SVG</strong> formats.</p>
<p>You can assign a custom model or texture by selecting <strong>Printer settings - General - Bed shape - Set</strong>.</p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-300x279.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-430x400.png 430w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-768x714.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/bed_shape_dialog-645x600.png 645w" alt="" width="429" height="399"></p>
<div class="note-callout">If the texture size doesn't match the bed size, the texture will be stretched to perfectly fit the bed. It is not currently possible for the texture to have elements outside of the print area.</div>
<div class="note-callout">The full path to the selected files is stored into "bed_custom_texture" and "bed_custom_model" Print profile variables.&nbsp;</div>
<h3>Exporting SVG textures from Adobe Illustrator</h3>
<p>The <a href="https://github.com/memononen/nanosvg">Nano SVG</a> parser, which PrusaSlicer uses, does not support every feature of the SVG format. We suggest the following workflow to correctly export SVG texture from Adobe Illustrator:</p>
<ol>
<li><strong>File - Export - Export As</strong></li>
<li>Tick&nbsp;<strong>Use Artboards</strong>&nbsp;to make sure that the resulting size is correct</li>
<li>In the <strong>SVG Options</strong> dialog pick:
<ul>
<li>Styling - <strong>Inline style (Internal CSS is NOT supported)</strong></li>
</ul>
</li>
<li>Confirm with&nbsp;<strong>OK</strong></li>
</ol>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-300x254.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-473x400.png 473w, https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-768x649.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/illustrator_export-710x600.png 710w" alt="" width="413" height="349"></p>
<h3>Performance</h3>
<p>In order to prevent graphics issues due to the excessively detailed print bed textures not fitting into the GPU memory, we implemented the following strategies to cope with the low GPU memory issues:</p>
<ul>
<li>We only rasterize the print bed texture to a high resolution of 8192x8192 pixels if the graphics card supports OpenGL 3.0 and newer, or if there is a Retina display connected to a Mac. Otherwise, a lower resolution 4096x4096 print bed texture is rasterized.</li>
<li>If the detected RAM size is less than 6GB the texture size is reduced by another 1/2 factor</li>
<li>The print bed texture is compressed with the <a href="https://github.com/Cyan4973/RygsDXTc">Real-Time DXT1/DXT5 C compression library</a>.</li>
</ul>
<p>In addition to that, after the application start-up, a low-resolution print bed texture is loaded to the GPU first, while the higher resolutions are compressed and sent to the CPU progressively as they are ready.</p>

PrusaSlicer - Printables.com integration

<p dir="ltr">When you import multiple models or create many instances of the same model, arranging them on the print bed could be very time-consuming. PrusaSlicer features an auto-arrange tool that distributes the objects over the entire Print bed with a reasonable gap between them. Auto-arrange can be initiated either by hitting the <span class="key">A</span> key or by picking the Auto-arrange from the top toolbar.</p>
<h3 dir="ltr">Partial arrangement</h3>
<p>The Auto-arrange tool can be used to arrange only a subset of the objects on the bed while keeping the position of unselected objects unchanged. This can be achieved by selecting the set of objects and hitting the Arrange button while holding down the <span class="key">Shift</span> key, or pressing the <span class="key">Shift</span> + <span class="key">A</span> hotkey.</p>
<h3>Customizable gap and automatic rotation</h3>
<p>Starting with PrusaSlicer 2.3, <strong>right-clicking the Auto-arrange icon</strong> in the top toolbar opens a dialog to tune the distance between objects and to allow rotation of objects around their Z-axis during the arrangement. As a result, you’ll be able to fit more parts on the build plate.</p>
<p>You can either use the slider to set the spacing or enter an exact value by Ctrl+Left mouse button clicking into the text field.</p>
<p>The current spacing and rotation settings also affect the <a href="http://help.prusa3d.com/article/copy-paste-instances_1769#fill-bed-with-instances">Fill bed with instances</a> function.</p>

<p>Food-safe 3D printing is not as simple as it might seem. Here we outline some of the challenges. We also recommend you to check out <a href="https://blog.prusaprinters.org/how-to-make-food-grade-3d-printed-models_40666/">our blog article</a> where we present our research of the process.</p>
<h3>Materials</h3>
<p>PETG, and sometimes PLA, are hailed in the 3D printing community for being chemically neutral and as practically food-safe materials. Your soda plastic bottles, food containers, and salad boxes are made from PET, a close relative of PETG.</p>
<p>The problem, with all 3d-printed objects, in general, is that they are made from layers. The grooves in between those layers are a seedbed for bacteria as they are almost impossible to clean properly, and will hold residue.</p>
<p>Another issue is color-pigment and unknown additives. These might not be as neutral to your body as pure plastic. It is also hard to say exactly how much there is of these substances. Natural/pure PETG-filament without any color, would be your best bet, but it's hard to say exactly what is in it. Some filaments are FDA-approved, but often with an asterisk like "Approved except red, orange, and pink". In <a href="https://blog.prusaprinters.org/how-to-make-food-grade-3d-printed-models_40666/">our blog article</a> we map out which of our Prusament filaments you can and can not use.</p>
<div class="tip-callout">There are, however, food-safe certified epoxy coatings that you can apply to your printed model.</div>
<h3>Application</h3>
<p><strong>Waterbottle, no. Cookiecutter, maybe.</strong> There should not be much problem to 3d-print your own custom cookie-cutters, but as the layer-lines will collect food, bacteria will grow, so this will be something you want to throw away after some use.</p>
<p>The same goes for soap and detergent if you think you can just wash it. The layer lines can absorb these chemicals, which later can be released into something you want to consume.</p>
<h3>(M)SLA resin printers have practically no lines. Can't I use this?</h3>
<p>Again, no. There can be uncured resin and other contaminants on and in the print. There are bio-compatible resins out there, but these are highly specialized and very expensive. They also rely on special considerations when curing and in post-processing.</p>
<h3>Nozzle</h3>
<p>The nozzle you use also makes a difference. The standard brass nozzle is <strong>not considered food-safe</strong>, as it wears out. It is a consumable. Where does the worn material go? Into your print. Therefore, a soft brass nozzle just won't do. You would need a stainless-steel or a titanium nozzle if you are even considering printing with food in mind.</p>
<h3>So what can I do?</h3>
<p>There are epoxy resin coating-materials out there that have been deemed suitable. There is also the option of using 3d-prints simply as a mold with suitable materials and manufacturing methods. We have done some research and you can read more about food-safe 3D printing in <a href="https://blog.prusaprinters.org/how-to-make-food-grade-3d-printed-models_40666/">this blog article</a>.</p>
<h3>Conclusion</h3>
<p>It is theoretically possible, but special preparations and post-processing is required. If you really want to, it is not as simple as getting some PETG, and printing what you want. Do proper research, so you do not put anyone's health or safety at risk!</p>
<div class="warning-callout"><strong>We do not recommend using 3d-prints as food-containers etc!</strong></div>
