PLA: 4 hours at 45C. ABS/PETG: 4 hours at 65C. Nylon: 8 hours at 70C. TPU: 5 hours at 50C. Times increase with higher ambient humidity.
| Material | Temp °C | Time | Hygroscopic |
|---|---|---|---|
| PLA | 45°C | 4h | Low |
| ABS | 65°C | 4h | Moderate |
| Nylon | 70°C | 8h | Very High |
| TPU | 50°C | 5h | High |
Wet filament pops, crackles, and hisses during printing. You may see stringing, bubbles in the extrusion, poor layer adhesion, and a rough surface finish.
Yes. Food dehydrators work well but are 15% slower than dedicated filament dryers due to less precise temperature control. Set to the same temperature as recommended for the material.
PLA is the least hygroscopic common filament but still absorbs moisture over weeks/months. If stored unsealed for over a month in humid conditions, drying for 4 hours at 45C will improve print quality.
