The ELEGOO Heat-Bed Spray Adhesive Glue is a handy consumable for improving how well your 3D prints stick to the build surface. If you’ve ever had prints warp, lift at the edges, or just fail to adhere to PEI, glass, or steel plates, this spray helps fix that. It comes in a 100 ml bottle, is easy to apply, works with many filament types (PLA, ABS, PETG, TPU, etc.), and rinses off easily. It’s especially useful for people using Elegoo printers (Neptune series) but works just as well on other machines.
