Have you ever seen your 3D print lift off the build plate mid-print, ruining hours of work and meters of filament? The problem is almost always the same: the first layer. 3Dbooster Lock is the Made in Italy spray adhesive that solves the problem at its root: one spray lasts multiple prints, works with PLA, PETG, ABS, ASA, PC and TPU, and cleans off with a sponge and warm water.
