Bambu Labs PLA-CF is a state-of-the-art 3D printing filament combining PLA with carbon fibre for superior mechanical strength and rigidity. Perfect for high-stress tasks like automotive components and drones, PLA-CF offers ease of printing with high performance.

Physical Properties

  • Density: Typically in the range of 1.3–1.4 g/cm³
  • Heat Deflection Temperature (ISO 75 0.45MPa): 55°C
  • Tensile Strength: Significantly improved compared to standard PLA, often exceeding 70 MPa due to carbon fibre reinforcement

Aesthetic Quality

The filament exhibits a matte, textured finish characteristic of carbon fiber composites, lending a high-tech, professional look to the printed parts. The material is generally available in darker or natural tones, which aligns with its industrial and functional focus.

Durability and Usage

PLA-CF from Bambu Labs offers excellent mechanical strength and rigidity, surpassing standard PLA in terms of tensile strength and durability. The carbon fiber reinforcement makes it more suitable for functional and load-bearing applications, including automotive components, drones, and various mechanical parts. It is also more resistant to wear, making it ideal for parts that experience friction or movement.


Due to its high mechanical strength, PLA-CF may require specialized post-processing techniques. It can be sanded, machined, and painted, but these tasks usually require higher-grade tools and materials. Specialized adhesives or coatings may be necessary for optimal results, given its enhanced durability and resistance.

Environmental Impact

PLA-CF maintains some of the biodegradability of PLA but is less eco-friendly due to the carbon fiber content, which is not biodegradable. While PLA is derived from renewable resources, carbon fibers are not, making the material a mixed bag in terms of environmental impact. Responsible disposal or recycling is encouraged to mitigate its ecological footprint.

In summary, Bambu Labs PLA-CF filament offers an innovative combination of PLA’s ease of use and carbon fiber’s high performance. It is suitable for a range of advanced and functional 3D printing applications requiring increased strength, rigidity, and durability. Though not as environmentally friendly as pure PLA, its performance characteristics make it a compelling option for specialized, high-stress tasks.
