FDM Nylon 12CF (Carbon Fiber)
Production-grade Thermoplastic
FDM Nylon 12CF™ is a carbon-filled thermoplastic with excellent structural characteristics. The material is comprised of a blend of Nylon 12 resin and chopped carbon fiber, at a loading of 35% by weight.
This combination produces one of the strongest thermoplastics for our Fused Deposition Modeling (FDM®) 3D printing service. It has the highest flexural strength of any FDM thermoplastic, resulting in the highest stiffness-to-weight ratio.
