A new three-dimensional printing using carbon-fiber-reinforced thermoplastic (CFRTP) tape has been developed. A thin CFRTP tape 0.6 mm wide and 0.18 mm thick is molten in the nozzle and drawn to the base material surface with compression by the head surface of the nozzle. Through this process, a thin layer 1.5 mm wide and 0.05 mm thick is adhered to the base material. Along the curved route in which the circumferences of the outside and inside circles are different, fibers cross over each other with no wrinkles with the same route length. In a lamination test on an eye-glass route with eight layers, defects in the lamination of a new layer were reduced by adding a hot compression ring around the nozzle head. Some future subjects were investigated for the development of a 3D printing using CFRTP.
