Wet Filament Wet filament refers to hygroscopic 3D printing materials that absorb moisture from the environment, leading to inconsistent extrusion, bubbles, and poor layer adhesion. It affects dimensional accuracy, mechanical strength, and surface finish. Common wet filaments include Nylon, PETG, and PVA. Proper storage in airtight containers with desiccants and filament dryers prevent moisture absorption. Advanced drying systems use temperature-controlled ovens or vacuum chambers for effective drying. Proper handling ensures reliable flow, dimensional stability, and high-quality prints. |
