4. Tips for Best Results
With a glass transition temp of 106°C and HDT of 92-97°C, Fibreheat ASA-GF is suitable for parts requiring high strength and heat resistance. The addition of chopped glass fibers provides a tensile modulus of 2871 MPa (XY) and bending modulus of 2751 MPa (XY).
- To achieve optimal print quality, use a ≥0.4mm nozzle at 250-270°C, with the build plate at 100-110°C.
- Retraction distance of 1-5mm at 1800-3600 mm/min is recommended.
- Keeping the printer enclosed and heated to 60-80°C can help avoid warping.
- After long-term storage, the filament must be dried at 70-80°C for 4-6 hours before use.
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.
