SUNLU PETG-CF Carbon Fibre 3D Printer Filament – 1kg
Carbon Fibre Reinforced PETG for Strong, Lightweight, and Professional Prints
SUNLU PETG-CF is a high-performance carbon fibre reinforced PETG filament designed for makers and professionals who need enhanced strength, rigidity, and dimensional stability without sacrificing ease of printing. By combining PETG’s durability and chemical resistance with finely milled carbon fibre, this filament delivers lightweight, stiff, and visually refined parts ideal for functional and structural applications.
Enhanced Strength and Rigidity
The added carbon fibre significantly improves stiffness and reduces flex, making PETG-CF ideal for brackets, mounts, housings, and load-bearing components. Prints maintain their shape under stress while remaining lighter than standard PETG parts.
Improved Dimensional Stability
Carbon fibre reinforcement minimises warping, shrinkage, and deformation during printing. This results in more accurate parts, cleaner edges, and consistent results across long or complex print jobs.
Excellent Surface Finish
SUNLU PETG-CF produces a smooth, matte, professional-grade finish that naturally hides layer lines. This makes it suitable for both functional parts and visually exposed components where appearance matters.
Easy Printing with PETG Reliability
Compared to nylon-based carbon fibre filaments, PETG-CF remains relatively easy to print. It offers strong layer adhesion, low odour during printing, and improved resistance to moisture compared to standard nylons.
Technical Specifications

Recommended Hardware
Due to the abrasive nature of carbon fibre, a hardened steel, bimetal, or tungsten carbide nozzle is strongly recommended. Brass nozzles will wear rapidly.
Ideal Applications
Structural brackets and mounts
Mechanical and functional components
Lightweight jigs and fixtures
Drone parts, tool holders, and enclosures
Professional prototypes requiring stiffness and precision
Strong, Stable, and Built for Performance
SUNLU PETG-CF Carbon Fibre Filament delivers the perfect balance between strength, printability, and professional appearance. It is an excellent choice for users who want carbon fibre performance without the complexity of high-temperature nylon systems.
