❗Note Before Printing： The PPA-CF Black Filament is engineered for use with nozzles 0.4mm or larger as it contains Carbon Fiber. ✅For 0.4mm+ nozzles. ❌Nozzles smaller than 0.4mm will CLOGGED. DO NOT USE ✅Hardened steel nozzles are required. ✅Printer MUST have enclosures.  Bambu Lab A1/A1 Mini is not recommended Fibreheart PPA-CF 3D Printer Filament is crafted with PPA (Polyphthalamide), a high-performance engineering thermoplastic, and fortified with carbon fiber, this filament is engineered to excel in high-stress applications, offering superior toughness, chemical resistance, and thermal stability. Smart Fiber Reinforcement:Evenly disperses 15% carbon fibers for enhanced strength, heat resistance, and reduced warping for consistently high-quality prints. Extreme Environment Durability:Its exceptional thermal resistance ensures the filament maintains nylon's toughness and abrasion resistance even in high-temperature environments. Superior Printability:Low hygroscopicity ensures better printability and dimensional stability compared to PA6 Nylon. Precision for Demanding Applications:Carbon fiber technology creates a strong mesh skeleton structure, and its precision ensures accuracy in every part. It is ideal for automotive and industrial parts requiring high thermal and mechanical resilience.
