Claim 4:
5. A method for manufacturing a three-dimensional shaped object, comprising:
a plasticizing step of plasticizing at least a part of a shaping material containing a thermoplastic resin to generate a plasticized material;
a fiber introducing step including at least one of a step of introducing a covered fiber material, which is a first fiber material covered with a covering material, into the plasticized material after being discharged from a nozzle opening, and a step of introducing the covered fiber material into the shaping material or the plasticized material before being discharged from the nozzle opening;
a cutting step of cutting the covered fiber material after the fiber introducing step, the cutting step including a step of cutting the covered fiber material by operating a discharge amount control mechanism, which is configured to control a discharge amount of the plasticized material from the nozzle opening, that is provided upstream of the nozzle opening to cut the covered fiber material disposed between the discharge amount control mechanism and a cutter blade provided in an introduction flow path that delivers the plasticized material to the nozzle opening; and
a shaping step of shaping a three-dimensional shaped object including the covered fiber material,
wherein the plasticizing step includes, in a plasticizing apparatus that includes a flat screw that has a groove forming surface in which a groove portion is formed, a facing portion that has a facing surface facing the groove forming surface and that is formed with a communication hole communicating with the nozzle opening, and a heater that is configured to heat the flat screw or the facing portion, a step of guiding at least a part of the thermoplastic resin supplied between the flat screw the facing portion to the communication hole while plasticizing the thermoplastic resin by rotation of the flat screw and heating of the heater.
