Limited Stock


 Double-sided Satin PEI Powder-coated Spring Steel Sheet for the Original Prusa i3 MK2.5, 2.5S and MK3, MK3S, MK3S+.

The Satin Spring Steel Sheet further expands the Prusa line-up of print sheets. In terms of printing properties, the Satin sheet sits between the smooth and textured variants. Its powder-coated surface with 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 and more. A vast majority of materials can be printed without a separation layer (e.g. glue).

Polycarbonate - prints better on satin (compared to smooth and textured sheets) - when printing with PC often, glue stick layer is recommended to prevent possible damage to the sheet.

Filament compatibility


  • Suitable for both PLA and PETG
  • Lightly textured surface finish
  • No need for Windex for PETG
  • No need for glue stick with FlexFill 98A
  • Wide range of supported filaments, including advanced materials, for instance PC Blend
  • Easy maintenance and good adhesion qualities


  • Acetone causes the surface to quickly deteriorate
  • Prints from ASA, PC Blend require a brim / skirt / shield around the print
  • Live Z value needs to be readjusted if you switch sheets
  • DO NOT use sharp metal objects (e.g. a spatula) to remove the print!


Never clean the Satin powder-coated spring steel sheet with acetone! Doing so will create microfractures in the texture, which will make the surface deteriorate over time. Learn more about printing on the Satin powder-coated steel sheet in the Prusa knowledge base.
