The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.
This print sheet is specially designed to print polypropylene-based filaments, especially the Prusament PP Carbon Fiber Black. The PP-type materials have generally a lower adhesion on textured or satin print sheets. This sheet has a special surface finish that increases the adhesion and is perfect for Prusament PP.
The PP sheet has a lightly textured surface finish similar to the Satin Powder-coated Steel Sheet.

WARNING:
Never clean the PP sheet with acetone! Acetone partially dissolves the sheet‘s surface, leaving stains. It may also negatively affect both adhesion properties and the sheet’s lifespan.
Note:
Consumable parts, such as PEI sheets (smooth, textured, nylon 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. Only defective sheets on arrival are covered by warranty.
As a result of the temperatures to which the plate is exposed during printing, its surface gradually becomes glossier or may develop smaller, duller areas. This visual change does not adversely affect the printing properties and is not considered a reason for a warranty claim.
