Spring Steel Sheet With Smooth Double-sided PEI

This product is a replacement Spring Steel Sheet With Smooth Double-sided PEI for the Original Prusa i3 MK3/S and MK2.5/S heatbeds.

Update:

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.

Not compatible with

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.

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

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.

Tiny dots may appear on the PEI-Ultem steel sheet surface. These can slightly affect the finished print bottom surface. However, they do not impact the printing process, reliability in any way. We do not consider these dots a reason for a warranty claim.

after 2.5a, the TF-21 is unfortunately already gone on both sides. Only PETG was printed. A total of about 5 rolls of Prusa PETG. The TF-21 was ideal for PETG, no warping, really good adhesion.

getting supreme adhesion for single walled objects with no bottom layer. HIPS (needs to be wiped with acetone after each print though) Also works really well for PLA (better results with 90% IPA wipe between prints than 99% IPA (has to do with stuff nonsolvable in IPA probably) Gives a very shiny finish on PLA (not what I'm looking for so I use textured sheets for PLA wchich works absolutely fine even with problemativ prints as long as you clean properly (!). Big advantage with this is that it can be cleaned with acetone. don't use acetone containing oil residues though!!!
