The 3D printing filament vacuum kit is a portable household vacuum appliance for optimum filament storage, especially for some with high water absorption rates such as PVA, EPA, EPA-CF, EPA-GF, ABSMAX, TPU-95A, ETC. If your filaments are open and not used up, you can use this kit to store your filaments to prevent them from absorbing water and impairing print quality. This text is machine translated.
