The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.
Powder coating directly on metal makes it very hard to damage this build plate. If a heated nozzle crashed into it, the metal can dissipate the heat. Powder coating also gives the surface a distinct textured look that will be visible on your prints. The textured surface hides most of the mechanical damage caused by tools. Only the top of the small bumps can be scratched, which will not imprint on the bottom of the model. This surface is used on our print farm, look at the printed parts you have on your printer for reference.

Never clean the Textured PEI Powder-coated spring steel sheet with acetone! Doing so will create microfractures in the PEI texture, which will make the surface deteriorate over time. Learn more about printing on the Textured PEI Powder coated steel sheet on our Blog.
