High-Strength Carbon Fiber PETG for Functional 3D Printing

The Black 1.75mm 3DXTech CarbonX™ CF PETG Filament 0.75kg is a carbon fiber reinforced PETG material engineered for advanced functional 3D printing applications requiring enhanced stiffness, dimensional stability, and professional-grade surface quality. Manufactured by 3DXTech, CarbonX™ CF PETG combines the durability and printability of PETG with the performance benefits of carbon fiber reinforcement.

Designed for makers, engineers, robotics builders, product designers, and industrial users, this composite filament produces lightweight yet rigid parts suitable for demanding mechanical and structural applications. The matte black carbon fiber finish delivers a premium appearance while minimizing visible layer lines for cleaner final parts.

Carbon fiber PETG is widely used for end-use components, engineering prototypes, tooling, brackets, drone parts, automotive projects, and lightweight assemblies where standard PLA or PETG may lack sufficient rigidity.

Key Features & Benefits

Carbon Fiber Reinforced PETG

Carbon fiber additives improve stiffness, dimensional stability, and structural performance compared to standard PETG.

Lightweight and Rigid Parts

Produces strong lightweight components ideal for engineering and mechanical applications.

Professional Matte Surface Finish

The carbon fiber texture helps reduce visible layer lines and creates a premium industrial appearance.

Excellent Layer Adhesion

Maintains strong interlayer bonding for durable functional parts and long-term reliability.

Improved Dimensional Stability

Carbon fiber reinforcement helps reduce shrinkage and improves print precision on complex parts.

Easier Printing Than Many Engineering Materials

Offers more manageable printability compared to higher-temperature engineering polymers while still delivering excellent strength.

Functional End-Use Performance

Suitable for structural prototypes, workshop tools, machine components, and production-grade applications.

Typical Applications

3DXTech CarbonX™ CF PETG is commonly used for:

• Functional engineering prototypes
• Robotics components
• Automotive brackets and mounts
• Drone and RC parts
• Tooling and jigs
• Structural assemblies
• Mechanical housings
• Manufacturing fixtures
• Lightweight replacement parts
• Industrial and workshop applications

Its combination of stiffness and manageable printability makes it popular among advanced hobbyists and professional users alike.

Printability & Material Performance

Carbon fiber reinforced PETG offers a balance of strength, rigidity, and printability that appeals to users seeking higher-performance parts without the extreme temperature requirements of specialty engineering materials.

Users can expect:

• Strong and rigid printed parts
• Reduced flex compared to standard PETG
• Excellent layer bonding
• Matte textured surface finish
• Improved dimensional accuracy
• Reduced visible layer lines
• Reliable functional performance

Because carbon fiber materials are abrasive, a hardened steel nozzle or wear-resistant nozzle is strongly recommended for long-term printing durability.

For best results:

• Use a hardened nozzle
• Print with a heated bed
• Dry filament before use if needed
• Use controlled cooling settings
• Ensure proper first-layer adhesion
• Tune retraction settings for optimal extrusion consistency

Material & Compatibility Information

This filament is designed for FDM/FFF 3D printers that support 1.75mm filament.

Compatible with many modern desktop and professional 3D printers including:

• Bambu Lab
• Prusa
• Creality
