In some cases, you might want to cut a model into multiple pieces before printing:

  • the model is too big to be printed in one piece
  • you only want to print a part of a model
  • a part of the model needs a different print orientation for added strength
  • printing the model in one piece would require a needlessly large amount of support material

PrusaSlicer provides an advanced cutting function:

  • Cut models at any angle
  • Select which parts to separate and which to keep connected
  • Generate connectors and dowel pins for easy assembly

Select the object and press the C key or pick the Cut tool 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.


You can also hold down the Shift 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.


For both the top and bottom part, you have the option to:

  • Keep - toggles whether the part should remain in the 3D view or be deleted after the cut
  • Place on cut - rotates the parts so that the cut area aligns perfectly with the heatbed
  • Flip - rotates the model upside down after cutting

Select which parts to separate and which to keep connected

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.


Adding connectors and dowel pins

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.

The Plug type will add extra geometry to one side of the cut and subtract it from the other side. The Dowel type will subtract the pin from both sides and generate and extra object to print as the connector.
