It is an engineering filament for functional parts that need to stay stiff and dimensionally stable when they get hot or take load — gears, brackets, mounts, tooling, drone and RC parts, end-use mechanical components. This is the high-temp grade: it runs hotter and resists more heat than the common PA12-based \"PAHT-CF\" you see at hobby prices.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat it prints well:\u003c\/strong\u003e rigid, low-warp parts with a matte carbon finish. The carbon fiber forms a mesh skeleton through the matrix, so prints come off the bed with good dimensional stability and minimal warpage for a nylon. The base resin is a modified high-temp nylon with low moisture sensitivity (saturated absorption ~1.37%, roughly a tenth of plain PA6), so mechanical properties hold up far better than standard nylon once parts are in service.\u003c\/p\u003e\n\n\u003ch3\u003eHardware you need\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardened nozzle, non-negotiable.\u003c\/strong\u003e Carbon fiber is abrasive and will chew a brass nozzle in a few hundred grams. Run a hardened-steel, DLC-coated, tungsten-carbide, or ruby nozzle. Phaetus specs hardened steel or above, with a heating block of at least 12mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-temp all-metal hotend.\u003c\/strong\u003e Nozzle temperature is \u003cstrong\u003e300-320°C\u003c\/strong\u003e — above what many stock hotends and PTFE-lined setups can handle.
