【Extreme Stiffness & Heat Resistance】- SUNLU PA6-CF reinforced nylon filament blends 80% PA nylon with 20% carbon fibers. The result is a significant upgrade in structural rigidity, tensile strength, and heat resistance, while also ensuring outstanding layer adhesion for reliable, durable prints.
【Industrial-Grade Durability】PA6-CF ideal for functional prototypes and end-use parts that must endure stress, this material excels in applications requiring high torsional, tensile, and impact strength. Use it to print durable components like gears, brackets, tool housings, fan blades, automotive prototypes, and robust sports equipment.
【High-Temperature Performance (209°C/408°F)】- Featuring a heat deflection temperature significantly higher than many common filaments like Easy PA, PC, or ASA, this material is perfect for parts exposed to heat. It’s suitable for automotive under-hood components, machinery covers, heat-resistant fixtures, and other high-temperature environments.
【Recommended Print Settings】- For successful prints, use a nozzle temperature of 270-290°C (518-554°F) and a heated bed at 50-70°C (122-158°F). Print speeds between 50-150mm/s are recommended. To maximize the heat resistance and strength of your part, annealing at 80-130°C for 5-12 hours is highly advised.
【Essential Printing Tip: Dry Before Use】- For optimal results, dry this filament before printing. Recommended settings: 80°C for 24 hours or 110°C for 4 hours. Due to its abrasive nature, use a hardened steel or other wear-resistant nozzle for best performance and to prevent wear on standard copper-alloy nozzles.
【Precision 1.75mm Diameter】- Features a consistent 1.75mm diameter with a tight tolerance of +/- 0.03mm. This high dimensional accuracy ensures reliable extrusion and broad compatibility with the vast majority of FDM 3D printers on the market.
【Universal Spool Compatibility】- The spool is designed for wide compatibility: 203.2mm (8") diameter, 63.5mm (2.5") width, and a 55.88mm (2.2") hub hole. It fits most popular printers, including models from Bambu Lab (H2D, X1, P1 series with AMS), Prusa, Creality, and more.
【Factory-Fresh Vacuum Sealing】- Every spool is vacuum-sealed with a desiccant pack inside. This industrial packaging locks out moisture and dust during shipping and storage, guaranteeing that your filament arrives perfectly dry and ready to deliver excellent print quality.
【SUNLU Main 3D Products】- SUNLU offers a variety of high-quality 3D printing products, including 3D printer filament, engineering filament,filament dryer, filament connector, 3D printer resin, resin curing box, and other accessories.
