Why Filament Storage Matters
Most filaments are hygroscopic — they absorb moisture from the air. Wet filament causes popping, stringing, and poor surface finish.
Which Filaments Absorb Most Moisture?
- Nylon: Extremely hygroscopic
- PETG/TPU: Moderately hygroscopic
- PLA/PLA+: Low absorption but still benefits from dry storage
- ABS: Low moisture absorption
Dry Box Solutions
Use a dedicated filament dry box like the ANTINSKY FilaBox with hygrometer and desiccant compartment.
Drying Methods
- Filament Dryer: PLA at 45-50°C, PETG at 60-65°C, Nylon at 70-80°C
- Food Dehydrator: Budget-friendly alternative
Signs of Wet Filament
- Popping/crackling sounds during printing
- Excessive stringing
- Bubbles on print surface
