Polymaker Fiberon PETG-RCF08 Filament – 500g, 1.75mm
Carbon Fibre Reinforced PETG for Strong, Dimensionally Stable Prints
Polymaker Fiberon PETG-RCF08 is a high-performance PETG-based filament reinforced with 8% recycled carbon fibre, designed to deliver enhanced stiffness, improved dimensional stability, and a refined matte surface finish. It combines the ease of printing associated with PETG with the mechanical advantages of carbon fibre reinforcement, making it suitable for both functional and aesthetic applications.
Enhanced Strength with Improved Print Stability
The addition of recycled carbon fibre significantly increases rigidity while reducing shrinkage and deformation during printing. This results in parts with better dimensional accuracy and reduced warping compared to standard PETG, making Fiberon PETG-RCF08 ideal for larger prints and mechanically demanding components.
Clean Matte Finish and Consistent Layer Bonding
Fiberon PETG-RCF08 produces a uniform matte surface that helps mask layer lines and enhances the overall appearance of printed parts. Strong interlayer adhesion ensures durable prints with reliable mechanical performance across complex geometries and extended print runs.
Easier Printing than Traditional Engineering Filaments
Unlike many high-performance composites, PETG-RCF08 remains relatively easy to print and does not require a fully enclosed printer. It offers stable extrusion and predictable behaviour, making it accessible to advanced hobbyists and professionals alike while still delivering engineering-grade results.
Professional Printing Requirements
Due to the abrasive nature of carbon fibre reinforcement, the use of a hardened or wear-resistant nozzle is recommended. A heated bed is advised to achieve optimal adhesion and print consistency, especially for larger parts.
Moisture-Protected, Ready to Print
Each 500g spool is vacuum-sealed to protect the filament from moisture absorption, ensuring smooth extrusion and consistent print quality from the first layer to the last.
