Frequently Asked Questions
What temperature should I set my filament dryer for PPE?
Set your filament dryer to 100°C for PPE. This applies to iDryer, Sunlu S1, Creality Filament Dryer, and similar devices.
How long does PPE need to dry?
Dry PPE for at least 4 hours at 100°C. Heavily absorbed spools may need up to twice as long.
Can I print PPE directly from the dryer?
Yes — printing directly from an active dryer is the best approach for moisture-sensitive filaments. iDryer supports pass-through printing with active drying during your print.
