Polymaker Fiberon PETG-rCF08 Carbon Fiber Reinforced PETG Filament 1.75mm 1kg Black

PETG filament reinforced with 8% chopped carbon fiber delivers exceptional stiffness and dimensional stability for demanding functional parts. This advanced material combines the ease of printing with high strength and low warping, making it ideal for engineering applications.

Advantages

Carbon fiber reinforcement significantly increases rigidity and reduces shrinkage compared to standard PETG. The result is precise, warp-free parts with excellent layer adhesion and a professional matte finish. The material maintains high impact resistance and heat tolerance, suitable for functional prototypes and end-use components.

Suitable for

• Functional prototypes and mechanical parts
• Tooling, jigs, and fixtures
• Drone frames and RC components
• Automotive brackets and housings
• High-strength replacement parts
