Bambu Lab PAHT-CF Black (1.75mm, 500g) is a high-temperature polyamide reinforced with short carbon fibre, delivering an exceptional combination of stiffness, strength and thermal stability for professional engineering applications. PAHT stands for High-Temperature PA, offering a heat deflection temperature significantly above standard nylon, making it suitable for parts in engine bays, industrial machinery, electronics housings and aerospace jigs.

The carbon fibre loading gives PAHT-CF its characteristic rigid, matte black finish and dramatically reduces thermal expansion and moisture absorption compared to unfilled nylons. This makes it dimensionally stable even in challenging environments. It requires an abrasion-resistant nozzle (hardened steel or tungsten carbide) and a dry filament environment for best results.

Key features

• High heat deflection temperature (up to approximately 150-180C) for parts in thermally demanding environments.
• Carbon fibre reinforcement provides excellent stiffness and dimensional stability under load and temperature.
• Low moisture absorption compared to unfilled PA - more stable and consistent printing with proper drying.
• Lightweight alternative to metal for structural brackets, jigs and fixtures.
• Requires abrasion-resistant nozzle (hardened steel or tungsten carbide) due to the CF content.
• Also available in 1kg (210000005766) for production runs - the 500g spool is ideal for smaller runs, prototyping or trying PAHT-CF for the first time.

Compatible with: Bambu Lab X1 series, P1 series with high-temp and hardened hotend
