Carbon-Fibre-Reinforced Filaments — Maximum Strength and Rigidity

Carbon-fibre-reinforced (CF) filaments are composite materials that blend short carbon fibres into a polymer matrix. The result is a filament with exceptional rigidity, low weight, and dimensional stability — properties unavailable in standard filaments.

Our range includes PLA-CF (easiest to print, good rigidity), PETG-CF (better chemical resistance), ASA-CF (UV resistant with carbon fibre), PA6-CF (strongest, the industry standard for functional parts), PAHT-CF (heat resistant up to 150 °C), and PET-CF (high strength and chemical resistance). All are printed on our Bambu Lab X1C with hardened steel nozzles.

Carbon-fibre filaments are ideal for drone frames, automotive prototypes, tools and jigs, robotic components, and any application where the strength-to-weight ratio is critical. Pricing is higher than standard filaments, but the mechanical performance justifies the investment.
