eSun – PETG-CF (Black) PETG-Carbon Fibre Composite 1.75mm

eSUN’s PETG-CF material is reinforced with carbon fibres to significantly enhance strength, rigidity, and hardness while reducing warping. It is widely applicable in tooling fixtures, prototyping, electronics, and the manufacturing of automotive parts.

Compared to standard PETG, PETG-CF shows significantly improved rigidity and strength. Testing results reveal that PETG-CF has a flexural modulus of 2500 MPa—an increase of 203%—and a flexural strength improvement of 190%.

PETG-CF offers excellent printability, reducing issues like stringing, oozing, and nozzle clogging during printing, with minimal warping.

PETG inherently possesses specific waterproof and chemical-resistant properties. With the addition of carbon fibres, its performance stability is further enhanced, providing some resistance to corrosive substances.

Unlike traditional black carbon fibre materials, PETG-CF offers a richer colour palette, including DARK GREY, ANTIQUE BRASS, BLACK RED, DARK GREEN, and DARK BLUE. Its carbon fiber composition gives printed models a matte, frosted finish—perfect for users seeking a premium aesthetic.

Usage Recommendations and Precautions: Carbon fibre materials tend to cause greater wear on printer nozzles. When printing with carbon fibre materials, it is recommended to use a hardened steel nozzle. Additionally, the material is sensitive to moisture. It is recommended to dry the filament at a temperature of 65°C for at least 8 hours before printing.
