Filament Flashforge PA-CF 3D printer filament 0.5 kg, 1.75 mm (carbon fiber reinforced polyamide)

Flashforge PA-CF is a 1.75 mm carbon-fiber-reinforced polyamide filament supplied on a 0.5 kg spool. Formulated to combine the toughness and chemical resistance of nylon with added stiffness and dimensional stability from chopped carbon fibers, this filament is intended for users who need stronger, heat-resistant printed parts compared with standard nylon. The material is compatible with printers that support nylon-type filaments and allow higher nozzle and bed temperatures as required for polyamide-based materials.

Advantages

Carbon-fiber reinforcement increases rigidity and reduces warping and shrinkage typical for unfilled polyamide, while maintaining good layer adhesion and surface finish. The filament provides improved heat resistance and better dimensional stability under load compared with common nylon filaments. Because it is provided in a 0.5 kg spool with 1.75 mm diameter, it fits most desktop and prosumer direct-drive and Bowden systems that accept nylon blends, assuming appropriate hardware and settings are used.

Suitable for

• Functional prototypes requiring higher stiffness and heat resistance
• Mechanical parts such as brackets, gears and mounts
• Enclosures and housings exposed to elevated temperatures
• Small production runs of load-bearing components

Key specifications

• Material: Carbon-fiber-reinforced polyamide (nylon composite)
• Diameter: 1.75 mm
• Spool weight: 0.5 kg
• Form: Solid filament on spool
• Typical properties: increased stiffness, improved dimensional stability, enhanced heat resistance

How to use

Load the 1.75 mm filament into a 3D printer equipped to handle nylon-type materials and carbon-filled composites. Use a hardened steel or other wear-resistant nozzle to avoid premature wear from abrasive carbon fibers. Set nozzle and bed temperatures appropriate for polyamide filaments; enable an enclosed build chamber or use a heated enclosure if available to reduce warping. Optimize print speed, retraction and cooling settings to balance surface quality and interlayer adhesion. Dry the filament before printing if it has absorbed moisture; store the spool in a dry container with desiccant when not in use.

Recommendations

For best results, use a hardened nozzle, print with an enclosed chamber or heated bed, and pre-dry filament at the manufacturer-recommended temperature and time. Adjust slicer settings for slower print speeds and higher extrusion temperatures compared with standard PLA or ABS to achieve reliable layer bonding and dimensional accuracy.
