PLA-CF

Material type: Plastic

PLA-CF is a composite reinforcement material made by mixing carbon fiber powder into a traditional polylactic acid (PLA) plastic matrix. It is designed to retain the advantages of PLA for easy printing while significantly improving its mechanical properties.

Material advantages

PLA-CF has excellent mechanical properties. Hard enough to resist bending. Suitable for the high precision of assembly parts, its enhanced rigidity and strength make it suitable for printing load-bearing parts.

Material shortcomings

The adhesion between the layers may be slightly affected by the presence of carbon fiber. Adequate printing temperatures and proper cooling need to be ensured for optimization; The support surface is rough and difficult to sandy.

Recommended description

Although carbon fiber is added to PLA-CF, the density does not increase much, and the finished product may be lighter or similar to pure PLA parts of the same volume, but the strength and quality are much higher. This is a huge advantage for applications that pursue lightweight.
