Fibreheart™ PPA-CF Filament by Siraya Tech is a high-performance engineering filament crafted for demanding applications. Made from PPA (Polyphthalamide) and reinforced with 15% carbon fiber, it offers superior toughness, chemical resistance, and thermal stability. The Smart Fiber Reinforcement evenly disperses carbon fibers for enhanced strength, heat resistance, and reduced warping. Its Extreme Environment Durability ensures it maintains nylon's toughness and abrasion resistance even in high-temperature settings. With superior printability, low hygroscopicity guarantees better results and dimensional stability than PA6 Nylon. Ideal for automotive and industrial parts requiring high thermal and mechanical resilience. Designed for 0.4mm+ nozzles with hardened steel and an enclosed printer. Not recommended for Bambu Lab A1/A1 Mini.
