Textured Powder-coated

The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.

Powder coating directly onto metal makes this build plate very difficult to damage. 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 affect the bottom of the model. This surface is used on our print farm, please check the printed parts on your printer as a reference.

Smooth PEI

The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets. The spring steel sheet with smooth double-sided PEI uses the same PEI sheets as on the MK2/S. It is the best option for printing PLA, and it has good adhesion with almost all materials. The bottom of your prints will be smooth.

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

Update:

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

Satin Powder-coated

The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.

The Satin sheet further expands our line-up of print sheets. In terms of printing properties, the Satin sheet sits between the smooth and textured variants. Its powder-coated surface with lightly textured matte finish offers an optimal level of adhesion, especially when printing PLA and PETG materials. It is fully compatible with a wide range of common and less-common filaments, such as ABS, ASA, FlexFill 98A, Polycarbonate and more. A vast majority of materials can be printed without a separation layer (e.g. glue).

Polycarbonate - prints better on satin (compared to smooth and textured sheets) - when printing with PC often, glue stick layer is recommended to prevent possible damage to the sheet.

PA Nylon Powder-coated

The MK52 heatbed has embedded high Curie temperature magnets. These magnets are able to firmly hold removable spring steel sheets.

This print sheet is designed specifically to print polyamide-based filaments, especially the Prusament PA11 Carbon Fiber Black. PA11-type materials generally have lower adhesion on textured or satin print sheets. This sheet has a special surface finish that increases adhesion and is perfect for Prusament PA11.

IMPORTANT!

The surface of this sheet should only be cleaned with plain water. Using common agents like IPA or acetone will lead to a rapid degradation of the surface. The use of a glue stick is no longer necessary and recommended. To clean grease-stained areas, use plain water with a drop of dish soap.

Note:

Consumable parts, such as PEI sheets (smooth, textured, nylon, etc.) are not covered by the 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 the warranty.

As a result of the temperatures to which the sheet is exposed during printing, its surface gradually becomes shinier or may develop smaller, matte areas. This visual change does not negatively affect printing properties and is not considered a reason for a warranty claim.

Please note that with the original Prusa MK4, the wear of PA Nylon sheets is particularly noticeable at the Z-probe points, where the nozzle leaves visible marks on the surface. This does not affect surface adhesion and general printability. You can examine the marks in our knowledge base article.
