About PA6-CF (Carbon Fibre Nylon)

PA6-CF is a carbon fibre reinforced Nylon 6 filament that delivers structural performance approaching metal while remaining printable on FDM machines. The short carbon fibre reinforcement dramatically improves stiffness (4430 MPa tensile modulus, 5460 MPa bending modulus) compared to any unreinforced FDM material.

We print PA6-CF on fully enclosed, high-temperature FDM machines with chamber temperatures up to 60°C, engineering-grade build plates, and glue bed preparation. Its 164°C heat deflection temperature and 102 MPa tensile strength make it the definitive choice for automotive brackets, aerospace fixtures, industrial clamps, and structural components that must survive real-world loading.

PA6-CF requires a hardened steel nozzle due to its abrasive carbon fibre content — our machines are fully equipped with 0.4 and 0.6 mm hardened nozzles for optimal CF surface quality and dimensional accuracy.

Frequently Asked Questions

PA6-CF is the top choice when you need the highest stiffness, structural strength, and heat resistance from an FDM material. Ideal for automotive brackets, industrial fixtures, aerospace components, robotic end effectors, and any part that must carry significant loads at elevated temperatures while remaining lightweight.

The carbon fibre reinforcement in PA6-CF dramatically increases stiffness (4430 MPa vs ~2000 MPa for standard PA6) and strength while slightly reducing elongation. It also significantly improves heat resistance. The trade-off is that PA6-CF parts are stiffer and slightly more brittle than standard nylon, and require hardened steel nozzles to print.

PA6-CF is highly hygroscopic — it absorbs moisture from the air that turns to steam during printing, causing stringing, layer defects, and weakened mechanical properties. We dry all PA6-CF filament at 80°C for 8–12 hours before printing and maintain a sealed, low-humidity print environment throughout the job.

PA6-CF can be drilled, tapped, and machined. It can be lightly sanded but the carbon fibre texture means it will not achieve a smooth surface finish — it retains a distinctive dark, matte CF appearance. It cannot be painted easily due to its surface texture and chemical resistance. It bonds well with two-part epoxy for assembly.

PA6-CF has a heat deflection temperature of 164°C at 1.8 MPa — the highest of all standard FDM materials we offer. This makes it suitable for under-hood automotive use, near heat sources, in industrial machinery, and for parts exposed to repeated thermal cycling between extremes.
