The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.
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 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.

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.
Consumable parts, such as PEI sheets (smooth, textured, etc.) are not covered by warranty as the coatings are designed to diminish over time unless failure has occurred due to a defect in materials or workmanship. Cosmetic damage, including but not limited to scratches, dents, cracks or other cosmetic damage is also not covered by the warranty (example of a cosmetic scratch that does not affect functionality). Only defective sheets on arrival are covered by warranty
