Filament BambuLab PAHT-CF 1.75 mm 0.5 kg Black — carbon-fiber reinforced high-temp 3D printing filament

BambuLab PAHT-CF 1.75 mm 0.5 kg Black is a carbon-fiber reinforced PAHT filament formulated for high-temperature, engineering-grade 3D printing. The filament combines a polyamide-based high-temperature matrix with short carbon fibers to deliver improved stiffness, dimensional stability and heat resistance compared with standard filaments. Supplied on a 0.5 kg spool with 1.75 mm diameter, this black filament is intended for functional parts, mechanical components and prototypes that demand enhanced mechanical performance and thermal stability during use.

Advantages

The carbon-fiber reinforcement increases tensile stiffness and reduces part deformation under load and elevated temperatures. The PAHT base provides higher heat deflection temperature and chemical resistance relative to typical PLA or ABS, enabling parts to retain shape in demanding environments. The 1.75 mm diameter ensures compatibility with a wide range of consumer and prosumer hotend systems, while the consistent spool format supports predictable extrusion and dimensional accuracy.

Suitable for

• Functional mechanical parts and housings
• High-temperature prototypes and fixtures
• Gears, brackets and structural components
• Tools and jigs that require stiffness and dimensional stability

Key specifications

• Material: carbon-fiber reinforced PAHT (polyamide high-temperature composite)
• Filament diameter: 1.75 mm
• Spool weight: 0.5 kg
• Color: Black
• Fiber type: short carbon fibers for stiffness and reduced creep
• Intended temperature range: designed for high-temperature printing and use (requires heated bed and high-temperature hotend)

How to use

Print BambuLab PAHT-CF using a 1.75 mm filament setup with a high-temperature hotend capable of the recommended extrusion temperatures for PAHT composites and a heated bed. Use an all-metal nozzle; hardened or coated nozzles are recommended to withstand abrasive carbon fibers. Ensure filament is dry before printing and store spools in a low-humidity environment or sealed with desiccant to prevent moisture uptake. Calibrate extrusion multiplier and retraction to balance surface finish and stringing for carbon-fiber reinforced materials.

Usage recommendations

For best results, use a hardened steel nozzle, print with enclosure or controlled ambient temperature to reduce warping, and dry filament at manufacturer-recommended conditions before use. Avoid applications requiring electrical insulation or extreme impact toughness; consider post-processing options such as annealing or surface finishing to improve dimensional accuracy or surface appearance if needed.
