Product Details
- BUILT FOR PERMANENT OUTDOOR USE — Premium ASA carbon fiber filament retains full UV and weather resistance. No brittleness, no yellowing after months of sun exposure — no protective coating required.
- LIGHTER BUILD — 15% chopped carbon fiber reinforcement boosts tensile strength and rigidity vs standard ASA. Creates strong, warp-free structural parts with reduced weight for functional applications.
- ULTRA LOW WARP & DIMENSIONALLY ACCURATE — Minimal thermal shrinkage ensures consistent, precision prints even on large builds. Far less prone to warping than ABS/ASA; works with most enclosed FDM printers.
- HEAT & CHEMICAL RESISTANT — Heat deflection temperature up to 90-100°C for reliable performance in warm environments. Resists oils, greases, and common chemicals — ideal for industrial and automotive parts.
- TANGLE-FREE & READY TO PRINT — 1kg spool with precision machine winding for smooth feeding. Vacuum-sealed with desiccant to stay moisture-free. For best results, use with a hardened steel nozzle.

Printing UniFilasTech ASA-CF
UniFilasTech ASA-CF in Black is ASA filled with chopped carbon fiber, and this listing is a 1kg 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.
