What is a filament dryer?
Filament dryers are essential tools for 3D printing. They allow you to recover wet filament. Spools of plastic used for printing can be degraded by moisture if left out in open air, which causes poor print quality and makes for fragile parts.
3D printing plastics are hygroscopic, which means that they almost always absorb moisture. This moisture damages the plastic at a molecular level, making drying your filament imperative.
How does a filament dryer work?
Filament dryers, like other dehydrators or industrial dryers, heat the air in a chamber to “cook” away moisture. Bonus features include rotating spool mounts for an evener distribution of heat
