kexcelled Carbon Fiber PET CF Filament 1.75mm 1KG, High Speed Carbon Fiber Reinforced PET 3D Printer Filament, High Strength & Low Moisture Sensitivity, Ultra-Low Warping 0.1%, Black

Product Details

• 【Superior Mechanical & Thermal Properties】Reinforced with premium chopped carbon fibers, this filament offers exceptional stiffness, tensile strength, and impact resistance. It maintains structural integrity under mechanical stress and provides higher heat resistance compared to standard PETG, making it ideal for demanding engineering applications.
• 【Low Moisture Sensitivity (0.1% Absorption Rate)】Unlike Nylon-based composites (PA-CF), our PET-CF features ultra-low moisture absorption (down to 0.1%). It stays stable even in high-humidity environments, preventing common issues like bubbling, stringing, or material degradation, ensuring a reliable "plug-and-play" experience.
• 【Engineered for High-Speed Printing】Unleash the full potential of your high-speed 3D printers. Optimized for speeds up to 250mm/s without compromising layer adhesion or surface quality. Perfect for professional-grade rapid prototyping and industrial production, significantly reducing your project lead times.
• 【Extreme Dimensional Stability & 0.1% Low Warping】Featuring advanced internal stress release technology, our PET-CF exhibits an industry-leading warping rate as low as 0.1%. Experience superior dimensional accuracy and precise tolerances for complex mechanical assemblies, jigs, and functional fixtures that fit perfectly every time.
• 【Precision Engineering & Wide Compatibility】Manufactured with a strict ±0.03mm diameter tolerance to ensure smooth extrusion and prevent clogging. Compatible with most FDM printers using 1.75mm filament. (Note: Hardened steel nozzle 0.6mm+ is recommended due to carbon fiber abrasiveness).

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.
