Prusa CORE One Smooth PEI Print Sheet – Reliable Adhesion & Smooth Prints

Upgrade your Prusa CORE One with the Smooth PEI Spring Steel Print Sheet, designed for flawless 3D printing. Made from high-quality double-sided PEI—the same material used in MK2/S sheets—this sheet provides excellent adhesion for PLA and works with most 3D printing materials.

The sheet attaches securely to the MK52 heatbed with embedded high Curie temperature magnets, ensuring it stays firmly in place while being easily removable. Prints stick when needed but release effortlessly once cooled, leaving you with a smooth, professional finish on the bottom surfaces.

Minor marks from the nozzle or tools may appear as slightly shinier spots; they do not affect performance. For a uniform surface look, simply resurface with a gentle circular motion using the hard side of a dry sponge.

Key Features:

• Smooth, double-sided PEI for PLA and versatile material adhesion

• Secure magnetic attachment to MK52 heatbed

• Removable and easy to maintain

• Ensures smooth bottom surfaces on all prints

• Compatible exclusively with the Prusa CORE One

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.
