Prusa Research Original Prusa Double-sided Textured PEI Powder-coated Spring Steel Sheet

$77.00

Double-sided textured PEI powder-coated spring steel sheet for the Original Prusa i3 MK3/S.

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.

WARNING: Never clean the textured powder coated sheet with acetone! Doing so will create microfractures in the PEI texture, which will make the surface deteriorate over time.

Note:

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. Only defective sheets on arrival are covered by warranty.

Why the price was increased?

The main reason is higher production costs than we expected when we originally announced prices. As we have written in several articles, the scrap ratio is so big that we had no other option than the price increase.
