PETG-CF Filament – Carbon Fiber Reinforced PETG for High-Strength Prints

3D Printing Canada’s PETG-CF (Carbon Fiber Reinforced PETG) is engineered for demanding applications that require maximum stiffness, strength, and dimensional stability. By reinforcing PETG with carbon fiber, this filament delivers a significant upgrade in rigidity and performance while remaining far easier to print than most high-end engineering materials.

The carbon fiber reinforcement dramatically reduces flex, creep, and warping, allowing parts to hold tight tolerances and maintain their shape under mechanical stress. Compared to standard PETG and PETG-GF, PETG-CF offers the highest stiffness and a premium, matte surface finish that helps hide layer lines.

PETG-CF prints cleanly with excellent layer adhesion and minimal odor, making it suitable for professional environments. It is an ideal choice when you need lightweight yet strong parts that can withstand real-world use without the complexity of nylons or other advanced composites.

From jigs and fixtures to brackets, mounts, and functional end-use parts, PETG-CF is built for applications where strength, rigidity, and long-term performance matter most.
