All filaments for 3D printing FDM / FFF are hygroscopic, i.e., they absorb moisture from the environment in which they are located.
Hygroscopicity is an undesirable effect in filaments for 3D printing. Plastic polymers consist of chains of molecules joined together. The absorbed water molecules destroy these chains, destroying the plastic and causing many problems when printing.
Don’t worry, the “wet” filament spools can be quickly dried, and proper storage can prevent future accidents.
Below, we look at how to recognize a wet filament, how to dry it, and finally how to store it correctly.
