Dustproof and Moistureproof Design The Filament Dryer uses a sturdy construction that protects your 3D printer filaments from dust and moisture, helping maintain material quality and print consistency with every use. Builtin Fan for Consistent Heating A builtin fan ensures uniform heat distribution inside the drying chamber, enabling faster temperature rise and eliminating hot spots that could damage filaments. 24Hour Timer with Adjustable Temperature Settings Includes a 24hour timer and three adjustable temperature settings to suit a range of filaments, including PLA, PETG, ABS, TPU, and others. Versatile Compatibility with Various Filament Sizes Supports filament diameters of 1.75 mm, 2.85 mm, and 3.0 mm, accommodating materials such as PVA, ePACF, ePAGF, PC, and more. Use scenarios Before printing with hygroscopic filaments such as PVA or Nylon, use the dryer to remove moisture for better extrusion and print quality. Dry filaments like PLA, PETG, ABS, or TPU to improve layer adhesion, reduce bubbling, and enhance overall print reliability. Manage filaments of different sizes (1.75, 2.85, 3.0 mm) and materials (including PC and reinforced variants) in one unit for versatile storage and drying.
