Smooth PEI plate for Prusa CORE One L
The double-sided smooth PEI plate for Prusa CORE One L and CORE One L+ provides good adhesion for almost all materials and works best with PLA. The underside of the print is smooth, and small details stay well attached to the plate.
Magnets in the heatbed hold the plate in place, so you can remove it together with the print and flex it to separate the model. We also offer plates for CORE One L: satin, textured, for PP materials and PA Nylon.

Is it a good choice for you?
A good choice if:
- You mainly print with PLA on a Prusa CORE One L
- You want a smooth, glossy underside on your prints
- You print small details that need to stay well attached to the plate
Consider another option if:
- You print a lot with PETG: choose the satin plate for CORE One L
- You print nylon: choose the PA Nylon plate for CORE One L
Frequently asked questions
Does it fit the standard CORE One?
No. The plate fits the Prusa CORE One L and CORE One L+. For the CORE One and CORE One+ you need a smaller plate.
Can I print PETG on it?
Yes, but do not clean the plate with isopropyl alcohol before printing, and use a separator if needed, because PETG sticks strongly to smooth PEI.
Is the plate covered by a warranty?
The manufacturer treats PEI plates as a consumable part that wears out over time. The warranty covers only manufacturing or material defects, not scratches and other signs of use.
