1KG PA6-CF Carbon Fiber Nylon 3D Filament 1.75mm, Heat Deflection Up to 209°C, 80% PA Nylon + 20% Carbon Fibers, Strong, Stiff, & Heat Resistant, Frosted Texture, Black, for Industrial Applications

SUNLU PA6-CF Carbon Fiber Nylon Filament — Made from 80% nylon and 20% carbon fiber, this industrial-grade filament offers exceptional strength, rigidity, and heat resistance up to 209°C. Ideal for printing durable mechanical parts like gears and fan blades, it ensures high precision (±0.03mm) and compatibility with most 1.75mm printers. Vacuum-sealed for dryness, delivering stable, professional-quality prints every time.

• Exceptional Strength & Heat Resistance – Made of 80% PA6 nylon and 20% carbon fiber, SUNLU PA6-CF offers superior stiffness, strength, and heat resistance with excellent layer adhesion, ideal for functional and durable parts.
• Perfect for Industrial & Engineering Applications – This filament is suitable for high-stress applications requiring torsional, tensile, and impact resistance, such as gears, screws, helmets, fan blades, toy car chassis, skateboard parts, and bicycle frames.
• High Heat Performance – With a heat distortion temperature up to 209°C, SUNLU PA6-CF outperforms common filaments like PLA, PC, and ASA, making it perfect for high-temperature parts like automotive exhausts, motor covers, pot handles, and kettle bottoms.
• Recommended Printing Settings – Nozzle: 270–290°C; Bed: 50–70°C; Speed: 50–150mm/s. For maximum heat resistance, anneal prints at 80–130°C for 5–12 hours. Bed adhesion works on most surfaces with a thin layer of PVA glue or Magigoo PA. Use hardened steel nozzles to prevent abrasion when printing with carbon fiber filament.
• Precision & Compatibility – Diameter: 1.75mm ±0.03mm, ensuring stable extrusion and compatibility with most FDM 3D printers. Spool dimensions: 203.2mm diameter × 63.5mm width × 55.88mm hub hole, compatible with printers like Bambulab H2D, X1 series, and more.
• Notes – Dry filament before printing (80°C for 24h or 110°C for 4h) to maintain optimal performance. Carbon fiber filament is abrasive; use wear-resistant nozzles for longevity.
