Satin steel sheet

This article is also available in following languages: 

The Original Prusa magnetic heatbed is designed to hold a removable double-sided flexible spring-steel sheet, designed specifically for easy removal of printed objects from the print surface.

Satin Sheet (color may differ from yours)	The underside of a printed object

The Satin sheet further expands our line-up of print sheets. In terms of printing properties, the Satin sheet sits between the smooth and textured variants. Its fine powder-coated surface with a lightly textured matte finish offers an optimal level of adhesion, especially when printing PLA and PETG materials. It is fully compatible with a wide range of common and less-common filaments, such as ABS, ASA, FlexFill 98A, Polycarbonate (PC), and more. 

Main attributes

• Suitable for both PLA and PETG
• Lightly textured surface finish
• Double-sided! Both sides can be used interchangeably.
• Prints automatically detach after the sheet cools down
• Wide range of supported filaments, including advanced materials (PC Blend, Polypropylene…)
• Easy maintenance and good adhesion qualities

Considerations

• Never clean the sheet with acetone! It will deteriorate the surface.
• Keep the sheet clean! Any grease will greatly reduce adhesion.
• Live Z value needs to be readjusted if you switch sheets. See Steel sheet profiles.
• Not scratch-resistant!!! Do not use metal spatulas etc. to remove the prints. We recommend printing a plastic spatula, like this one.
• Small PLA prints may require a Brim.
• Apply a glue stick when printing with TPU or TPEE.
• Prints from ASA and PC Blend have a lower adhesion on satin compared to on the smooth sheet. Prints often require brim and/or shield (skirt "Draft shield" around the object is a feature in PS 2.3)
• PC blend works perfectly with the clean satin sheet, however, it might cause wear after some time. If you print PC often, a glue stick separation layer is recommended to prevent potential damage to the sheet.

Maintenance

• Attracts fingerprints - A good indication of where your sheet is dirty/greasy and that you need to clean it. Clean with ~90% IPA when the sheet is cold. If ~90% IPA is not sufficient, clean with dishwasher soap. Do not leave the sheet wet! It has an anti-corrosion layer but is still not recommended.
• Never clean with acetone! Same issue as with the textured sheet (surface deteriorates)
• Some types of paper towels may leave traces on the sheet (fiber pieces). 

Filaments

We have done a lot of testing and compiled our results for you to use. To easily see how to prepare your sheet for any filament type, please see our Material table.

Prints don’t stick

If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in isopropyl alcohol ~90% and if the first layer height is set up perfectly, yet your print still does not adhere reliably to the print surface, check out First layer issues.
