This is a FACTORY SECOND product. It is rated as factory second due to cosmetic and visual defects only. The cosmetic and visual defects do not impact functionality. FACTORY SECOND products are completely unused. Non-second parts are also available in our store.

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. Using this sheet, the bottom of your prints will be smooth. PEI has excellent adhesion for many materials such as PLA, but adhesion with a few materials, such as PETG, can be strong enough to damage the surface. Glue stick, hairspray or window spray should be used for these materials.

You can also 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. 

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.

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.
