PETG-CF HF 3d printer filament works seamlessly with carbon harden nozzles. Need a strong, fast-printing, high-flow engineering filament with good chemical resistance that doesn't require an enclosed printer?
Siraya Tech PETG-CF HF filament is a high-speed carbon fiber PETG filament designed for those who demand performance. Whether you're working on functional prototypes, RC & drone parts, manufacturing tools, or high-impact brackets, this filament ensures precision, durability, and minimal warping.
Unlike traditional carbon fiber PETG, PETG-CF HF 3d printer filament is formulated for high-speed extrusion, enabling print speeds up to 150mm/s. The carbon fiber powder reinforcement enhances layer bonding, impact resistance, and stiffness, making it a reliable choice for professional and industrial applications. This enhanced stiffness translates to greater dimensional stability and accuracy in your prints.
PETG-CF HF filament combines the best of PETG with the advantages of carbon fiber. PETG offers excellent ease of use, low odor during printing, and good layer adhesion. It's also known for its balanced properties, bridging the gap between the ease of use of PLA and the strength of ABS. The addition of carbon fiber significantly boosts its strength, stiffness, and dimensional stability.
This filament features low moisture absorption, good chemical resistance, UV resistance and outstanding dimensional accuracy, making it ideal for outdoor parts.
