3D printer filament eSun EPETG-CF-P175BG1 1.75 mm carbon-fiber reinforced PETG, 1 kg, Blackish Green

eSun EPETG-CF-P175BG1 is a 1 kg spool of 1.75 mm carbon-fiber reinforced PETG filament in Blackish Green, created for FDM/FFF 3D printers. The composite material combines PETG's ease of printing and chemical resistance with short carbon fibers that increase stiffness and dimensional stability. This filament is intended for users who need stronger, more rigid printed parts than standard PETG while maintaining good layer adhesion and compatibility with typical PETG print settings.

Advantages

Carbon-fiber reinforcement enhances stiffness and reduces part deformation compared with unfilled PETG, while the PETG matrix keeps printing straightforward and provides good chemical resistance. The 1.75 mm diameter is compatible with most consumer and professional FDM/FFF machines. The Blackish Green color offers a subdued, technical appearance suitable for functional components and visible prototypes. Because the fibers are short and dispersed, the material preserves layer bonding and produces parts with improved dimensional accuracy.

Suitable for

• Functional mechanical parts requiring increased rigidity
• Prototypes and concept models with higher stiffness needs
• Tooling, jigs and fixtures exposed to mechanical load
• Enclosures and structural components where dimensional stability is important

Key specifications

• Material: PETG matrix reinforced with short carbon fibers
• Diameter: 1.75 mm
• Spool weight: 1 kg
• Color: Blackish Green
• Form: Filament for FDM/FFF 3D printing
• Mechanical characteristics: increased stiffness and improved dimensional stability vs. standard PETG

How to use

Load the filament into a compatible 1.75 mm extruder and use standard PETG print settings as a starting point. Adjust nozzle and bed temperatures according to your specific printer and filament behaviour; typical PETG ranges are a suitable reference but may require fine-tuning for optimum layer adhesion and surface finish. Because short carbon fibers are abrasive, install a hardened or wear-resistant nozzle and monitor first layers for proper extrusion. Ensure good part cooling and appropriate print speeds to balance surface quality and mechanical performance.

Usage recommendations

Use a hardened steel or other abrasion-resistant nozzle to prevent accelerated wear. Calibrate extrusion and bed leveling before long prints, and store the filament in a dry place or sealed container with desiccant to maintain consistent print quality. Test small samples to determine the best temperature and speed settings for your machine and intended application.
