Tips for Best Results
- Dry filament before and during printing for consistent results.
- If ambient temperature is low, allow extra time for the dryer to reach the set temperature (add 1 hour).
- Refer to the table for recommended drying times and temperatures for common materials:
| Material | Baking Temp | Time |
|---|---|---|
| PLA/PLA+ | 45-50 °C | 3-6h |
| WOOD | 45-50 °C | 3-6h |
| PETG | 50-55 °C | 3-6h |
| PVB | 50-55 °C | 3-6h |
| ABS/ABS+ | 60-70 °C | 3-6h |
| HIPS | 60-70 °C | 3-6h |
| PVA | 60-70 °C | 3-6h |
| ASA | 60-70 °C | 3-6h |
| TPU | 60-70 °C | 3-6h |
| PMMA | 60-70 °C | 3-6h |
| PA/PC | 60-70 °C | 3-6h |
Ensure filament is wound tightly, not loosely.
Troubleshooting
