Polymaker Fiberon PA612-CF15 Carbon Fiber Nylon Filament 1.75mm, Black, 0.5kg

Product Details

• 15% Carbon Fiber Reinforced PA612: Fiberon PA612-CF15 is a long-chain PA612 nylon reinforced with 15 wt% carbon fiber. It combines lower moisture sensitivity than PA6-based nylon with stronger mechanical performance than PA12-based materials, making it suitable for rigid functional parts, tooling, jigs, fixtures, and engineering prototypes.
• Strength Retention After Moisture Exposure: Typical TDS values include 91.9 MPa dry X-Y tensile strength and 83.1 MPa after the specified annealing and moisture-conditioning process. This balance makes the material useful for parts that may experience changing humidity during service.
• Heat Performance After Annealing: The heat deflection temperature reaches 175°C at 0.45 MPa after annealing at 100°C for 16 hours. Annealing also helps improve dimensional stability. HDT is a standardized test value and should not be interpreted as the continuous operating temperature of every printed part.
• Lower Moisture Sensitivity Still Requires Dry Storage: PA612-CF15 is less moisture-sensitive than PA6-based nylon but remains hygroscopic. Keep the filament below 20% relative humidity during storage and printing. Dry at 100°C for 10 hours before use if exposed to ambient humidity or if stringing, bubbles, or rough surfaces appear.
• Advanced Printer and Wear-Resistant Nozzle Required: Use an all-metal hotend, a 250–300°C nozzle, a 40–50°C build plate, and a hardened steel or ruby nozzle with the cooling fan off. A heated chamber is not required under the TDS conditions. Speeds up to 300 mm/s may be possible with a tuned profile. Before long prints, confirm smooth filament routing and unrestricted spool rotation.

Printing Polymaker Nylon-CF

Polymaker Nylon-CF in Black runs on the standard Nylon-CF profile below, and this listing is a 0.50kg spool. Nylon-CF is best suited to tough, wear-resistant mechanical parts like gears, hinges, and high-heat brackets. 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.
