The filament may suffer damage from moisture absorption. They are made up of linked chains of molecules and function as plastic polymers. These chains may be broken by the water molecules in the dampness, which will degrade the plastic and result in a variety of printing issues.When the 3d printing filament is baked, it often encounters the phenomenon that the coil melts. IEMAI 3D has specially upgraded it for the coil.
There are a few universal indicators that you have a damp spool, albeit different filaments absorb moisture at varying rates:
- Creating popping or crackling noises when ejecting
- Part strength and layer adhesion are significantly reduced
- inconsistent extrusion lines
- extremely stringy, blobby, or leaking
- prints with unusually rough or “fuzzy” surfaces
Drying your filament is usually a smart idea if you’re encountering any of the aforementioned symptoms. You could experience problems even after keeping nylon, PETG, PVA, and flexible materials out in the open for just one night.
