3D printer filament POLYMAKER PETG-rCF08 Fiberon 1.75 mm 750 g

POLYMAKER PETG-rCF08 Fiberon 1.75 mm 750 g is a PETG-based 3D printing filament reinforced with recycled carbon fiber, supplied on a 750 g spool. The material is formulated to provide improved dimensional stability and greater stiffness compared with standard PETG while retaining PETG's ease of printing and chemical resistance. The 1.75 mm diameter filament is intended for printers that accept PETG-type feed and extrusion temperatures, and is suitable for producing functional prototypes and mechanical parts that require enhanced rigidity and wear resistance.

Advantages

The addition of recycled carbon fiber increases tensile stiffness and reduces part deformation under load, leading to more stable prints for functional applications. Fiberon PETG-rCF08 maintains PETG's low warpage and good layer adhesion, while the recycled fiber content improves impact resistance and surface hardness. The 750 g spool format facilitates inventory management for small to medium print runs and reduces material handling compared with larger industrial spools.

Suitable for

• Functional prototypes and concept models requiring higher stiffness
• Mechanical components, brackets and mounts
• Parts exposed to moderate mechanical stress and wear
• Applications where dimensional stability and lower warpage are important

Key specifications

• Base polymer: PETG with recycled carbon fiber reinforcement
• Filament diameter: 1.75 mm
• Spool weight: 750 g
• Material properties: increased stiffness, improved dimensional stability, enhanced surface hardness
• Compatibility: for FDM/FFF printers that support PETG-type materials and 1.75 mm filament

How to use

Load the 1.75 mm filament into a printer configured for PETG materials and adjust extrusion temperature, bed temperature and print speed according to the printer manufacturer's recommendations for PETG-based composites. Begin with manufacturer-recommended temperature ranges and perform a small calibration print to fine-tune flow, retraction and cooling settings to reduce stringing and ensure consistent layer bonding. Use a heated bed and appropriate bed adhesion method to minimize first-layer issues; ensure the filament is dry before printing to prevent moisture-related defects.

Usage recommendations

For best results, dry the filament before use if stored in humid conditions, optimize nozzle temperature and flow for composite behavior, and consider a hardened or wear-resistant nozzle to reduce abrasion from carbon fiber. Monitor part orientation and infill to exploit the filament's stiffness where needed and follow standard safety practices for venting and handling when printing composite materials.
