Looking for strong bed adhesion in a build plate? We’ve got you covered. Introducing LayerLock Powder Coated PEI Build Plate—the reliable PEI build surface you need for your printer bed’s magnetic base. If painter’s tape or kapton tape haven’t been working for you, PEI is a wonderful alternative build surface known for successfully providing strong bed adhesion for standard filaments such as PLA, ABS, PETG, and flexibles such as TPU and TPE. Tired of watching your prints slip and slide on a build surface? LayerLock’s Powder Coated PEI Build Plate will have your prints locked down.


Thanks to the thin thickness of this spring steel build plate, you can easily flex off your print if they do not already pop off during cooling. No paint scraper, putty knife, or other sharp tool needed! Big bonus? This thin flexibility neither compromises the sturdiness of the plate nor the sturdiness of the surface. With the PEI powder coated into the high quality spring steel plate, you don’t have to worry about the PEI surface wearing out quickly from multiple prints or getting chips or scratches from sharp removal tools. Also, this build plate has double-sided powder coating PEI for double its longevity. Print more successful models, spend less on temporary PEI build surfaces, and save big in the long run.


Get the texture you never knew you wanted on your prints with LayerLock Powder Coated PEI Build Plate’s special surface. Smooth surface not giving you the exact look you’re seeking? Maybe smooth doesn’t work for your print’s particular function. With this PEI build plate, you’ll get a rugged texture that adds a charming and useful quality to your print. Smooth and sleek is beautiful, but some prints require a rougher surface for useful purposes such as reducing slippage. With the small bumps on the LayerLock Powder Coated PEI Build Plate, you’ll have a rough, but not harsh, surface that is both useful and aesthetically pleasing.

For success with nylon and nylon-based filaments, we do NOT recommend using PEI build surfaces. LayerLock Garolite Build Surfaces are best suited for this material. If interested in succeeding with polypropylene and OBC, check out LayerLock Build Surfaces for Polypropylene.


Installation is extremely easy for any printer setup. Attach the LayerLock Power Coated PEI Build Plate onto your printer’s magnetic base and align accordingly. Ensure the nozzle height is properly set by calibrating the z-height and leveling your print bed according to your specific printer’s guidelines. While adjustments to your z-height will be minor thanks to the build plate’s thin thickness, it is crucial that you follow this step before any attempts to print with this new set up. For a more detailed “How To Succeed” installation, check out our guide here. That's it! You're ready to print.


Cleaning the surface isn't necessary. However, if you find prints not adhering after a couple of prints due to debris or dust, use isopropyl alcohol with an IPA 91%+ on a paper towel or lint free cloth to wipe down the print area. As with any build surface, make sure you are not printing too close to the bed to avoid possibly infusing the filament into the build surface. If printing PETG, TPU, TPE, and RYNO, make sure the bed is heated BEFORE attempting to remove the print from the bed.
