Prusa MINI textured powder-coated sheet steel

The heated bed features embedded magnets with a high Curie temperature. These magnets are capable of holding removable spring steel sheets securely. The powder-coated surface with a textured, matte finish provides optimal adhesion, especially when printing with PLA and PETG materials. Warning: Never clean the satin powder-coated spring steel sheet with acetone! This will cause micro-cracks in the texture, leading to surface degradation over time.
