Store filament in vacuum-sealed bags with desiccant for long-term storage, or in a filament dryer set to 45°C for active use. PLA absorbs moisture slower than PETG, while Nylon and TPU are the most sensitive.
Moisture Absorption Rates
| Material | Time to Absorb | Drying Temperature | Drying Time |
|---|---|---|---|
| PLA | 12-24 hours | 45-55°C | 4-6 hours |
| PETG | 4-8 hours | 60-65°C | 4-6 hours |
| TPU | 4-8 hours | 50-60°C | 4-6 hours |
| Nylon | 2-4 hours | 70-80°C | 6-8 hours |
| Resin | N/A (liquid) | N/A | N/A |
Short-Term Storage (During Use)
Keep the spool in a sealed bag with desiccant between prints. A filament dryer set to 45°C provides active protection during printing.
Long-Term Storage (Months)
- Vacuum-seal the spool with 2-3 packets of silica gel desiccant
- Store in a cool, dark place (below 25°C)
- Label with the date opened
- Dry before use if stored for more than 3 months
Our Packaging
Every Yiqiu3D spool ships vacuum-sealed with food-grade desiccant in a moisture-barrier bag — tested through 35-day ocean transit simulations to arrive dry and ready to print.
Individual results depend on your printer, environment and application.
