The base is a high-temp PAHT (PPA-class) nylon reinforced with 25% chopped carbon fiber.\u003c\/p\u003e\n\u003ch3\u003eWhat makes it different: co-extrusion skin-core\u003c\/h3\u003e\n\u003cp\u003eUnlike conventional single-extrusion CF nylon, NexPA-CF25 is built with a skin-core structure: the abrasive carbon fiber sits in the core under a pure-resin outer skin. Two practical results — better Z-axis interlayer adhesion (the bond comes from fiber-free resin at the layer boundary), and reduced nozzle wear because less fiber contacts the nozzle wall on the way out. It is still an abrasive filament, but it is engineered to be gentler on hardware than typical CF nylon.\u003c\/p\u003e\n\u003ch3\u003eHardware you need\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardened nozzle is mandatory.\u003c\/strong\u003e Carbon fiber is abrasive — a brass nozzle will be destroyed. Use a hardened-steel nozzle at minimum; tungsten carbide is ideal for long runs.
