1. PRODUCT INTRODUCTION

  • High Strength and Durability: Carbon fiber reinforcement for tough, stress-resistant parts.
  • Advanced Reinforcement: 15% carbon fibers for superior mechanical properties and reduced warping.
  • Thermal Resistance: Vicat softening temperature reaches 230°C, which is very suitable for high-temp applications.
  • Low Moisture Absorption: Better printability and stability than PA6 & other nylons.
  • Stable accuracy: Chopped carbon fibers are evenly distributed to form a strong network solidified structure, ensuring high accuracy for complex engineering projects.

4. Preparing for Printing

Drying Dry at 100°C for 4-6 hours
Nozzle Use a hardened steel nozzle or higher grade Size request: 0.4mm and above
Heating Block 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: Store the filament in a dry box with relative humidity below 15%.
    • Resealing: Always reseal the filament packaging promptly after use to prevent moisture absorption.
    • Drying: If the filament absorbs moisture, dry it in an oven at 100°C for 4-6 hours to avoid issues like oozing, bubbles, and rough surface finish.

     

    7. Troubleshooting Common Issues

    (1) Moisture Absorption:
    Symptoms: Oozing, bubbles, rough surface finish.
    Solution: Ensure filament is stored in a dry box with humidity below 15%. If the filament absorbs moisture, dry it in an oven at 100°C for 4-6 hours.

    (2) Stringing and Oozing:
    Symptoms: 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:
    Symptoms: Rough or uneven surface finish.
    Solution: Ensure the filament is dry before printing. Adjust print speed and ensure
    consistent extrusion. Use a higher layer height if needed.
