Features include reversible printing surfaces—textured PEI leaves a patterned finish while smooth PET gives a glossy result—so you can choose the best surface for each filament. The spring steel construction is flat yet flexible for quick, tool-free part removal, and the magnetic backing makes installation and removal fast and secure.

Perfect for hobbyists and pros who want a reliable, multi-surface build plate that supports PLA, PETG, ABS and other common filaments. Improve first-layer adhesion, reduce warping, and speed up part removal with this versatile magnetic build plate.
