3D printer filament Flashforge PETG-CF 1.75 mm, 1 kg, Black

Flashforge PETG-CF 1.75 mm is a carbon-fiber–reinforced PETG 3D printer filament supplied on a 1 kg spool in black. The material offers increased stiffness and improved dimensional stability compared with standard PETG, making it suitable for functional parts, jigs and mechanical components that require higher strength and better heat resistance. The filament is intended for use with FDM/FFF printers that support reinforced or abrasive filaments and is best printed with a hardened nozzle to ensure consistent extrusion and to reduce nozzle wear.

Advantages

Carbon-fiber reinforcement increases stiffness and tensile strength while PETG base preserves toughness and good layer adhesion. The 1.75 mm diameter on a 1 kg spool provides compatibility with most desktop printers and long print runs without frequent spool changes. Compared with standard PETG, PETG-CF shows improved dimensional stability and better resistance to deformation under load and at raised temperatures.

Suitable for

• Functional prototypes and end-use parts
• Jigs, fixtures and tooling
• Mechanical components exposed to load or heat
• Parts requiring higher stiffness than standard PETG

How to use

Load the filament on a compatible FDM/FFF 3D printer and use a hardened or wear-resistant nozzle to minimise abrasion from carbon fibers. Recommended printing temperatures typically fall within the PETG range; start with manufacturer or printer community settings and adjust print temperature, bed temperature and print speed to optimise layer adhesion and surface quality. Ensure proper bed adhesion and cooling settings for your model geometry.

Usage recommendations

Use a hardened steel nozzle, enable retraction and tune printing parameters on a small test part before large prints. Store the spool in a dry place or sealed with desiccant to prevent moisture absorption which can affect print quality.
