Prusa Spring Steel Sheet

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 solution for printing PLA and it has great adhesion with almost all materials. The bottom of your prints will be smooth.

Smooth Double-Side PEI Sheet

The Smooth PEI sheet features a double-sided smooth PEI coating that provides very strong adhesion, especially for PLA. It is ideal when a perfectly smooth bottom surface is required and works well with common filaments such as PLA, ABS, ASA, HIPS, and some filled materials. However, materials like PETG and TPU can adhere too strongly, increasing the risk of damaging the PEI surface when removing parts unless a release agent (such as glue stick) is used. Maintenance involves regular cleaning with isopropyl alcohol, with occasional acetone cleaning allowed to restore adhesion. This sheet requires careful handling and proper Live-Z calibration to avoid surface damage.

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

Textured Powder-Coated Sheet

The Textured sheet uses a powder-coated PEI surface that creates a rough, matte finish on the bottom of printed parts. It is particularly well suited for filaments that tend to stick excessively to smooth PEI, such as PETG, TPU, TPE, and CPE, allowing easy part removal once the sheet cools. While it provides excellent adhesion for these materials, PLA may not adhere reliably and can detach during printing. Cleaning is typically done with isopropyl alcohol, and occasional washing with warm water and mild soap is possible, though not recommended frequently. This sheet is preferred when easy part release and functional surface texture are more important than a smooth finish.

Satin Powder-Coated Sheet

The Satin sheet offers a semi-textured surface that balances adhesion and release, making it the most versatile option. It works reliably with both PLA and PETG without the extreme adhesion issues of the Smooth sheet or the PLA adhesion problems of the Textured sheet. It is also compatible with ABS, ASA, flexible filaments, and even PC under proper conditions. The satin finish leaves a slightly matte but refined bottom surface. Cleaning should be done only with isopropyl alcohol, as acetone can permanently damage the coating. This sheet is ideal for users who frequently switch materials and want consistent results with minimal adjustments.

WARNING:

• 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.
