Filament BambuLab PPA-CF 1.75 mm 0.75 kg — Black

BambuLab PPA-CF 1.75 mm 0.75 kg — Black is a carbon-fiber reinforced polyphthalamide (PPA-CF) filament formulated for 3D printing functional, high-stiffness parts. Supplied on a 0.75 kg spool in 1.75 mm diameter, the material combines the mechanical strength and dimensional stability of PPA with the rigidity and surface wear resistance provided by short carbon fibers. The black color provides a neutral, professional appearance for mechanical components and prototypes while retaining thermal and chemical resistance characteristics typical of nylon-like engineering polymers.

Advantages

PPA-CF offers increased stiffness and improved surface hardness compared with unfilled PPA, reducing part deformation under load and extending service life in moving assemblies. The carbon-fiber reinforcement enhances heat resistance and dimensional stability, allowing for better performance in applications exposed to elevated temperatures or moderate chemical environments. Its formulation is suited to printing parts that require a balance of strength, wear resistance, and reliable layer bonding when processed on equipment compatible with nylon/PPA-type filaments.

Suitable for

• Functional prototypes and demonstrators that require higher stiffness
• Mechanical components such as gears, brackets, and bushings
• Structural parts that need improved thermal resistance and dimensional stability
• Applications where surface wear resistance and reduced creep are important

How to use

Print BambuLab PPA-CF using a 3D printer and hotend compatible with nylon/PPA-type filaments. Prepare a heated build platform and set appropriate bed adhesion methods such as a compatible PEI sheet, nylon-friendly adhesive, or a heated enclosure to reduce warping. Use elevated nozzle temperatures and a heated bed consistent with PPA processing guidelines, and adjust print speed, retraction, and cooling to account for the abrasive and stiffer nature of the composite. Install a hardened or wear-resistant nozzle to avoid accelerated wear from carbon fibers. Dry the filament before printing if it has been stored in humid conditions to prevent printing issues associated with moisture-sensitive engineering polymers.

Usage recommendations

For reliable results, run test prints to determine optimal nozzle temperature, bed temperature, and print speed for your specific printer setup. Use a hardened steel nozzle, enable an enclosure or controlled ambient temperature to minimize warping, and store the filament in a dry, sealed container with desiccant when not in use.
