Polymaker Fiberon PA12-CF10 Carbon Fiber Nylon Filament 1.75mm Black 0.5kg | For precise brackets, tools and durable functional parts; low moisture sensitivity, stable dimensions and low warping

Product Details

• Lightweight Carbon Fiber Nylon: Long-chain PA12 reinforced with 10% carbon fiber provides a balanced combination of strength, rigidity, dimensional stability, and low density for brackets, tools, jigs, fixtures, RC parts, and durable functional components.
• More Stable than PA6-Based Nylon: PA12-CF10 absorbs less moisture than PA6/66 and PA6-based carbon fiber materials, helping maintain more consistent dimensions and mechanical properties in changing humidity. Keep sealed and dry for reliable printing.
• Engineered Heat Performance: After annealing at 100°C for 16 hours, test specimens reach an HDT of 131°C at 0.45 MPa and 105°C at 1.8 MPa. These results are not continuous-use temperature ratings; actual performance depends on load, geometry, moisture, and print orientation.
• Use an All-Metal Hotend and Hardened Nozzle: Print at 280–300°C with a 40–50°C build plate and the cooling fan off. A heated chamber is not required. Carbon fiber is abrasive, so use a hardened steel, ruby, or other wear-resistant nozzle. Speeds up to 300mm/s are possible after calibration.
• Keep Dry and Plan for Final Dimensions: If the filament has absorbed moisture, dry at 100°C for 10 hours and print from a dry box when possible. For load-bearing parts, position the main load along the XY plane. Remove same-material supports before moisture absorption and verify dimensions after annealing.

Printing Polymaker Nylon-CF

Polymaker Nylon-CF in Black is Nylon filled with chopped carbon fiber, and this listing is a 0.5kg spool. The fibers make parts stiffer and more dimensionally stable than plain Nylon, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). The ranges below are for Nylon-CF, which usually prints a little hotter than plain Nylon. Nylon-CF is best suited to strong, stiff engineering parts that must also tolerate heat. 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, Polymaker and Prusament data. Heat resistance is the heat deflection temperature (HDT). Read our carbon fiber 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.
