Prusa smooth PEI printing plate

The MK52 heated bed has embedded high-temperature magnets. These magnets are able to hold the removable spring steel sheets securely in place. The spring steel sheet with smooth, double-sided PEI uses the same PEI film as the MK2/S. It's the best solution for printing PLA and has excellent adhesion to almost all materials. The underside of your prints will be smooth.

You may leave small marks on the print surface with your nozzle or tools; these will typically be shinier than the rest. This will not affect functionality or adhesion. However, if you want the entire print bed to have the same surface appearance, you can refinish it. The easiest way is to take the abrasive side of a dry kitchen sponge and gently wipe the affected area a few times in a circular motion.

Update:

The color of the steel sheet may differ from the product image (black, gold, green, etc.). The smooth PEI surface on the steel sheet, as well as all other properties, remain the same regardless of the color.
