Fiberon™ PETG-rCF08: PETG filament reinforced with recycled carbon fiber
Eco-friendly performance for technical applications
Fiberon™ PETG-rCF08 is a high-quality 3D printing filament made from PETG (polyethylene terephthalate glycol), reinforced with 8% recycled carbon fiber. This sustainable composite material combines PETG’s ease of printing and balanced properties with the added strength, stiffness, and unique surface finish provided by recycled carbon fiber.


Key features and benefits
Recycled carbon fiber content: Contains 8% recycled carbon fiber, making it an environmentally conscious choice without compromising performance.
Enhanced mechanical properties: Increased strength and stiffness compared to standard PETG – suitable for functional parts and technical applications.
Superior surface texture: The carbon fiber reinforcement provides a matte, professional finish that hides layer lines and enhances the aesthetics of the part.
Easy to print: Retains PETG’s reputation for minimal warping, excellent layer adhesion, and stable performance on most FDM/FFF 3D printers.
Moisture resistance: PETG’s natural resistance to moisture absorption is complemented by the carbon fiber, ensuring consistent print quality.

Ideal applications
Perfect for prototypes, functional parts, jigs, fixtures, and projects where sustainability, strength, and appearance are crucial.
Choose Fiberon™ PETG-rCF08 for your next project if you want a sustainable, strong, and visually appealing filament that is easy to print and designed for real-world applications.
