4. Preparing for Printing
-  To achieve optimal print quality, use a ≥0.4mm nozzle at 250-270°C, with the build plate at 100-110°C.
-
Nozzle: Use a hardened steel nozzle to handle the abrasive nature of carbon fiber reinforcement. If you're unsure, please contact the nozzle manufacturer, as there are many types available on the market.
- Keeping the printer enclosed and heated to 60-80°C can help avoid warping.
- Dried at 70-80°C for 4-6 hours.Only dry if filament shows signs of moisture.
- Fibreheat ASA-GF Black is an excellent choice for strong, UV-stable parts for outdoor use and functional applications. It enables production of large models with minimal warping when used with the proper heated enclosure setup.

6. Moisture Management
ASA filaments, including Fibreheart ASA-GF, are prone to moisture absorption, which can adversely affect print quality. Effective moisture management is therefore crucial.
(1) Storage: Store Fibreheart ASA-GF in the provided moisture-resistant aluminum bags when not in use. Using a dry box with desiccant, maintaining humidity below 15% is ideal for prolonged storage.
(2) Drying Filament: If moisture absorption is suspected, dry the filament at 70-80°C for 4-6 hours.
7. Troubleshooting Common Issues
(1) Stringing: Adjust retraction settings and print speed to tackle stringing. Also, ensure the filament’s moisture level is within acceptable limits.
(2) Poor Bed Adhesion: Improve bed adhesion using a glue stick or hairspray, or by slightly increasing the bed temperature. Make sure build plate temperature is set to at least 100C and an enclosure can greatly help with the results.
