BambuLab PAHT-CF Carbon Fiber Nylon Filament 1.75mm Black 1kg Spool

The BambuLab PAHT-CF filament combines a high-temperature polyamide base with carbon fiber reinforcement, delivering a material that stands apart from standard nylon or PLA-based composites. This 1kg spool of black 1.75mm filament is engineered for demanding applications where strength, stiffness, and thermal stability are non-negotiable. With a heat deflection temperature of 140°C and a tensile strength of 70 MPa, it brings industrial-grade performance to your desktop 3D printer.

Highlights

• Carbon fiber reinforced polyamide for exceptional rigidity and dimensional stability
• Low moisture absorption and low shrinkage ensure reliable prints with tight tolerances
• Recommended for use with hardened steel nozzles (≥0.4mm) and enclosed printers
• Compatible with Bambu Lab X1, P1, and A1 series, as well as other FDM printers with suitable hotend and enclosure

In daily use

When printing with PAHT-CF, maintain a nozzle temperature between 280-300°C and a heated bed at 90-110°C. The material's low moisture uptake means less worry about drying, but for best results, store filament in a dry box. This filament excels in producing functional prototypes, jigs, fixtures, and automotive components that must withstand heat and mechanical stress. The carbon fiber content gives a matte black finish and a stiffer feel compared to unfilled nylon, making it a favorite for engineers and makers who need parts that perform.
