Carbon fiber filaments is the stronger, sturdier, and more dimensionally stable versions of their base material. It is an exciting filament to work with as it is perfect for making parts for prototypes and other applications.
When standard filaments like PLA, ABS, PETG and nylon are reinforced with specially sourced carbon fibers, the result is an extremely stiff and rigid material with relatively little weight. These filaments are ideal for applications that require superior stiffness, ease of printing, improved dimensional stability, UV-resistance and lighter weight parts vs. standard structural materials.
When it comes to 3D printing, the material occupying the largest market share are photopolymers as compared to composite materials such as carbon fiber filled 3D printing materials.
To be able to compete with the traditional materials, these composite materials are necessary for 3D printing to be a viable technology and replace more conventional processes. As for composites, carbon fiber materials are a leading contender in the industry.
With carbon fiber reinforced into base materials for 3D printing, strength is added while keeping the prints lightweight. It is a cost-effective substitute to more expensive materials such as titanium.
Carbon fiber is a favorite material for applications in the automotive as well as the aerospace industries. As of the moment, the methods for introducing carbon fiber in the 3D printing processes is still limited.
- Have very good dimensional stability
- Have increased strenght and stiffness
- Tough and abrasive on extruders and may require hardened steel nozzles making it expensive using them
- Increased oozing during printing
- Mixture increases the brittleness of the filament
