Store and protect 3D printer filaments, optical equipment, and other sensitive material in a humidity-controlled environment. Also known as dry boxes and desiccator cabinets, these cabinets prevent moisture-sensitive 3D printer filaments, such as nylon, ABS, and polycarbonate, from becoming brittle, discolored, or broken. They also keep sensitive electrical and optical equipment, such as microscopes and lenses, free from mold and fungus.

These cabinets accommodate up to 3,200 lbs. of equipment and have larger interiors than standard electronics cabinets.
