Bambu Labs PETG-CF filament, a fusion of Polyethylene Terephthalate Glycol and carbon fibre, tailored for advanced 3D printing. Boasting superior mechanical strength, temperature resistance, and a sleek matte finish, this material excels in high-stress applications like automotive and mechanical assemblies.

Physical Properties

  • Density: Approximately 1.27–1.37 g/cm³
  • Heat Deflection Temperature (ISO 75 0.45MPa): 74°C
  • Tensile Strength: Enhanced compared to standard PETG, often exceeding 80 MPa due to carbon fiber reinforcement

Aesthetic Quality

The filament typically exhibits a matte, textured finish, imparting a sophisticated, industrial appearance to the printed parts. The presence of carbon fiber often limits the color options to darker or natural tones, focusing more on functional applications than aesthetic appeal.

Durability and Usage

Bambu Labs PETG-CF is known for its superior mechanical strength, rigidity, and temperature resistance compared to standard PETG. The carbon fiber reinforcement makes it an excellent choice for high-stress, functional applications, such as automotive parts, drones, and mechanical assemblies. The material’s enhanced durability also makes it suitable for parts that will be exposed to wear and movement.


Post-processing Bambu Labs PETG-CF can be a bit challenging due to its high mechanical strength. Techniques like sanding, drilling, and painting are possible but may require specialized tools or adhesives for optimal results. It’s worth noting that its chemical resistance can make certain forms of adhesive bonding or painting less effective without proper preparation.

Environmental Impact

PETG-CF is not biodegradable and the carbon fiber content further complicates recycling efforts. Although PETG itself is considered somewhat environmentally friendly due to its recyclability, the addition of carbon fibers reduces its overall eco-friendliness. As such, responsible disposal or recycling is essential to mitigate its environmental impact.

In summary, Bambu Labs PETG-CF filament offers a unique combination of PETG’s printability and the high-performance characteristics of carbon fiber. The resulting material is well-suited for advanced and functional 3D printing applications requiring increased strength, rigidity, and temperature resistance. While it may not be as eco-friendly as some other materials, its performance advantages make it an excellent choice for specialized, high-demand tasks.
