Quality Products & Reliable ServiceFiberon PA6-CF20 Carbon Fiber Nylon Filament 1.75mm, Black, 0.5kgFREE SHIPPINGContiguous 48 States30-DAY RETURNSShop With ConfidenceCUSTOMER SUPPORTContact Us Through Product OverviewFiberon PA6-CF20 is a high-performance carbon fiber reinforced Nylon 6 filament designed for rigid, heat-resistant functional parts. It combines PA6 with 20% carbon fiber to improve stiffness, strength, dimensional stability, and layer adhesion. It is suitable for functional prototypes, tooling, fixtures, automotive components, and industrial applications. Typical TDS values include a dry X-Y tensile strength of 109.3 MPa and a Young’s modulus of 8.64 GPa. After annealing at 100°C for 16 hours, printed specimens reach a heat deflection temperature of 215°C at 0.45 MPa. These values are typical reference data; final-part performance may vary depending on part design, print orientation, settings, and operating conditions. PA6-CF20 is moisture-sensitive and must be properly dried for reliable printing. Dry the filament at 100°C for 10 hours before use, then keep it below 20% relative humidity during storage and printing. Printing directly from a dry box is recommended to help reduce stringing, bubbles, rough surfaces, and inconsistent extrusion. Recommended settings include a 280–300°C nozzle, a 40–50°C build plate, an all-metal hotend, and the cooling fan turned off. A heated chamber is not required under the TDS conditions. Printing speeds up to 300 mm/s may be achieved with a properly tuned printer and profile. Because carbon fiber is abrasive, use a hardened steel, ruby, or other wear-resistant nozzle instead of a standard brass nozzle. For optimum heat resistance and dimensional stability, anneal printed parts at 100°C for 16 hours. Before long prints, confirm that the filament path is smooth, the spool rotates freely, and the material remains dry.Product Features

• 20% Carbon Fiber Reinforced PA6: Fiberon PA6-CF20 combines Nylon 6 with 20% carbon fiber for high stiffness, strength, dimensional stability, and strong layer adhesion. Designed for rigid functional parts, tooling, fixtures, and automotive or industrial prototypes.
• Engineering Performance After Annealing: Typical TDS values include 109.3 MPa dry X-Y tensile strength and an 8.64 GPa Young’s modulus. Heat deflection temperature reaches 215°C at 0.45 MPa after annealing at 100°C for 16 hours. Final-part performance may vary with design and printing conditions.
• Dry Before and During Printing: PA6 is moisture-sensitive. Dry the filament at 100°C for 10 hours before printing, then and print below 20% relative humidity, ideally from a dry box. Proper moisture control helps reduce stringing, bubbles, rough surfaces, and inconsistent extrusion.
• Advanced Printer Setup Required: Use a 280–300°C nozzle, a 40–50°C build plate, and an all-metal hotend with the cooling fan off. A heated chamber is not required; room-temperature chamber conditions are listed in the TDS. Printing speeds up to 300 mm/s are possible with a properly tuned profile.
• Use a Wear-Resistant Nozzle: Carbon fiber is abrasive, so a hardened steel or ruby nozzle is required instead of a standard brass nozzle. For optimum heat resistance and dimensional stability, anneal printed parts at 100°C for 16 hours. Before long prints, confirm smooth filament routing and unrestricted spool rotation.
