4. Preparing for Printing
Drying: PPA absorbs moisture, affecting print quality. Dry at 100°C for 4-6 hours if needed. Only dry if filament shows signs of moisture.
Nozzle: Use a hardened steel nozzle for carbon fiber abrasion.
Heating Block: Ensure the heating block is at least 12mm thick for optimal temperature stability.
Print Bed Surface Coating: Use a PEI sheet or apply a PVP glue coating on the print bed surface for better adhesion and to reduce warping.
*Note*:
- Only dry if filament shows signs of moisture.
- Drying is not required for the first unpacking unless the vacuum packing becomes damp.

6. Moisture Management
- Dry Environment: Keep filament in a dry box with <15% humidity.
- Resealing: Seal packaging immediately after use to prevent moisture.
-
Drying: If moisture is absorbed, dry at 100°C for 4-6 hours to avoid issues like oozing, bubbles, and rough surface finish.
7. Troubleshooting Common Issues
(1) Moisture Absorption:
Signs: Stringing, bubbling, uneven surface.
Solution: Keep filament in a dry box (<15% humidity). If damp, dry at 100°C for 4-6 hours.
(2) Stringing and Oozing:
Signs: Fine strings of filament between parts of the print.
Solution: Adjust retraction settings to 1-3mm at 1800-3600 mm/min. Ensure the filament is dry and the nozzle temperature is not too high.
(3) Surface Roughness:
Signs: Rough or uneven surface finish.
Solution: Ensure filament is dry before printing. Adjust print speed and ensure consistent extrusion. Use a higher layer height if needed.
(4) Warping:
Solution: Warping can occur due to the material cooling too quickly. To prevent this, maintain a consistent temperature environment around the printer, possibly using an enclosure to keep out drafts. Adjust the cooling fan settings to lower speeds or turn it off for the initial layers.
