Printing Tips
- Storage: Store the filament in a dry box with relative humidity below 15%.
- Drying: Find filament dryers here.
- PPA-CF: Dry at 100°C for 4 - 6 hours for best printing conditions
- PPA-CF Core: Dry at 80 - 100°C for ideal prints
- Printing: Enclosures are crucial to maintaining consistent print temperatures, and hardened nozzles are required due to carbon fiber reinforcement.
