High-Performance Prototypes That Are Light-Weight And Carbon-Fiber Reinforced

Nylon 12CF delivers the highest strength and stiffness-to-weight ratio of any our FDM materials, suitable for markets like aerospace, automotive, industrial & recreational manufacturing


Nylon 12CF is an FDM thermoplastic that is filled with carbon to provide structural characteristics. Build high-performance prototypes that stand up to the rigorous testing required of production parts. The combination of Nylon 12 resin and carbon fiber produces the strongest thermoplastic in FDM technology as it boasts the highest flexural strength of FDM thermoplastics. Its unique stiffness and strength allows manufacturers to replace metal components in jigs, fixtures, and production parts.
