【Exceptional Mechanical Performance】This carbon fiber reinforced polycarbonate filament delivers superior stiffness and strength with high abrasion and impact resistance. Ideal for structural components, brackets, fixtures, and functional parts that require durability. 【Extremely High Temperature Resistance】With a heat deflection temperature of up to 147°C, this filament maintains structural integrity under elevated temperatures, making it suitable for applications exposed to heat. 【Strong Chemical Resistance】Offers superior resistance to harsh acids, alkalis, oils, fuels, and industrial cleaners. Perfect for chemical valves, fuel systems, and environments prone to corrosion. 【High Print Quality】Featuring consistent dimensional stability and a diameter accuracy of +/-0.03mm (1.75mm), this filament ensures smooth extrusion with reliable layer bonding and bed adhesion. Helps reduce warping and shrinkage during printing. 【Professional Matte Surface Finish】The carbon fiber reinforced texture minimizes visible layer lines and produces a refined matte surface finish. Suitable for both functional parts and visible components where aesthetics matter. 【Printing Tips & Settings】For optimal results: ①Dry at 80°C for 5–8 hours before use; ②Preheat printer heating at 80-90°C for 12 hours; ③Use a hardened steel or tungsten carbide nozzle (0.4–0.6mm); Recommended settings: Nozzle Temperature: 250–280°C; Hotbed Temperature: 80–100°C; Printing Speed: 30–100mm/s.
