Continuous Fiber Reinforcement
CFR process starts with FDM 3D printing, which forms the outer shell and infill of the part using a nylon composite, typically a thermoplastic filled with short-strand chopped carbon fibers. A secondary nozzle is then used to lay long-strand continuous fibers to reinforce the part, similar to rebar in concrete.
