LD LAC is an adhesive spray designed for 3D printing. Its main purpose is to improve bed adhesion and prevent warping during printing. Essentially, you spray it onto the print surface before starting your print, and it helps the first layer stick better, reducing failures due to warping or detachment. The cans are typically labeled as “LD LAC Adhesive Spray for 3D Printer” and come in sizes like 400 ml.

It’s particularly useful when printing materials that tend to lift at the edges, like ABS, PETG, or flexible filaments, and is often used on glass or other smooth print beds.
