Product Details
- 8% Carbon Fiber Reinforced ASA: Fiberon ASA-CF08 combines ASA with 8 wt% carbon fiber to increase rigidity and dimensional stability while maintaining the UV and weather resistance associated with ASA. Designed for outdoor housings, fixtures, brackets, tooling, and functional prototypes.
- Mechanical and Heat Performance: Typical TDS values include 43.5 MPa X-Y tensile strength, 69.1 MPa X-Y bending strength, and a 3.61 GPa X-Y Young’s modulus. Heat deflection temperature reaches 103°C at 0.45 MPa. Final performance varies with part design and printing conditions.
- For Outdoor and UV-Exposed Parts: ASA provides resistance to UV exposure and changing weather conditions, while carbon fiber creates a rigid, matte surface. Suitable for exterior housings, automotive prototypes, agricultural equipment, brackets, and other functional components.
- Rigid Filament - Handle with Care: The unprinted filament may snap if bent tightly. Maintain a bending diameter above 60 mm, avoid sharp turns, and keep the feed path smooth and direct. Store and print below 20% relative humidity; dry at 90°C for 6 hours if the material has absorbed moisture.
- Printing Requirements: Use a wear-resistant nozzle, 260–280°C nozzle temperature, 90–100°C build plate, and keep the cooling fan off. An enclosed printer is recommended to reduce rapid cooling and cracking. Print in a well-ventilated area, and allow parts to cool naturally before removal.

Printing Polymaker ASA-CF
Polymaker ASA-CF in Grey is ASA filled with chopped carbon fiber, and this listing is a 0.5kg spool. The fibers make parts stiffer and more dimensionally stable than plain ASA, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). Few makers publish separate ASA-CF settings, so the ranges below are for plain ASA; expect to print toward the top of them. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our ABS & ASA filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Nozzle Compatibility
Carbon fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.
Based on Bambu Lab and Prusa guidance. More in our carbon fiber filament guide and nozzle types guide.
