Qidi PET-CF
Qidi PET-CF is a composite filament made from PET (Polyethylene Terephthalate) reinforced with chopped carbon fibers, engineered for strong, stiff, and dimensionally stable 3D printed parts. It offers an excellent combination of printability, mechanical strength, and thermal resistance, making it a versatile alternative to nylon-based carbon fiber composites — with less warping and easier handling.
Benefits
High stiffness and dimensional stability
Good heat resistance
Excellent chemical resistance
Lightweight yet strong
Limitations
Lower flexibility and impact resistance compared to unfilled PETG or nylon
Post-processing may fray fibers
Surface finish may be rough
Industries
Qidi PET-CF is commonly used in industrial design, prototyping, robotics, functional end-use parts, and mechanical fixtures. It’s especially favored in engineering applications that demand strength, stiffness, chemical resistance, and dimensional stability without the print difficulty of nylon-based carbon fiber composites. Typical parts include structural brackets, machine components, jigs, fixtures, drone frames, and housings where lightweight strength is critical.
