Kingroon PA6-CF Filament 1.75mm, Carbon Fiber Nylon 6 3D Printer Filament, High Strength High Rigidity Heat Resistant for Functional Parts and Industrial Tooling, 1kg (2.2lbs) Black Filament

Product Details

• 【High strength, stiffness & heat resistance】Kingroon PA6 Cf Filament keeps parts rigid under heavy loads – tensile strength ≥76MPa, flexural modulus 4980MPa, heat deflection 153°C for engine bays and heat tooling. The carbon fiber nylon filament 1kg spool (≈330m) enables rapid design validation and low‑volume production without outsourcing.
• 【Low warp, strong layer adhesion & dry to prevent defects】Kingroon Pa filament uses dual‑laser inspection – diameter 1.75mm (tolerance ±0.02mm) to reduce clogs. Fully automatic precision winding minimizes tangling for consistent feeding. Carbon fiber drastically reduces shrinkage – with bed 70‑100°C, no edge warping. Enclosed printer + hardened steel nozzle ensure strong layer fusion and excellent z‑axis strength.
• 【For engineers, tuners & diy makers】Mechanical engineer, automotive tuner, drone racer? Kingroon pa6‑cf filament is made for you. High strength, stiffness, heat resistance, wear resistance, impact resistance – suitable for industrial workshops, auto garages, or engineering labs. Print strong jigs, engine‑bay parts, drone arms – replace metal or injection‑molded parts. Iterate fast, get functional parts immediately.
• 【Built for real‑world applications】Tired of parts breaking under high heat and pressure? This black pa6‑cf carbon fiber nylon is designed for engine‑bay components, production‑line wear‑resistant jigs, racing drone arms, and high‑strength functional prototypes. Heat deflection 153°C, flexural strength 123MPa, impact strength 12.4kJ/m² – warp‑resistant, heat‑resistant, oil & solvent resistant. Easily print throttle gaskets, inspection fixtures, drone frames. Finished parts are strong, heat‑resistant, and resist chemicals and solvents – ready for workshops, garages, repair shops, or even under the hood.
• 【Kingroon quality & support】Kingroon pa6 cf filament comes vacuum‑sealed with desiccant – low moisture out of the box. Pa‑cf filament is highly hygroscopic – must dry at 60-70°C for 8‑12 hours before use to avoid stringing and bubbles. Complete printing parameters provided (print temp 250‑280°C, speed 30‑60mm/s). For any quality issues, contact us for prompt after‑sales support.

Printing Kingroon Nylon-CF

Kingroon Nylon-CF in Black is Nylon filled with chopped carbon fiber, and this listing is a 1kg 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.

Based on Bambu Lab and Prusa guidance. More in our carbon fiber filament guide and nozzle types guide.
