Claim 10:
11. A three-dimensional shaping apparatus, comprising:
a plasticizing unit configured to plasticize at least a part of a shaping material containing a thermoplastic resin to generate a plasticized material;
a discharging unit having a nozzle opening;
a fiber introducing unit having at least one of a function of introducing a covered fiber material, which is a fiber material covered with a covering material, into the plasticized material after being discharged from the nozzle opening, and a function of introducing the covered fiber material into the shaping material or the plasticized material before being discharged from the nozzle opening;
a discharge control mechanism configured to control a discharge amount of the plasticized material from the nozzle opening, the discharge control mechanism being provided upstream of the nozzle opening;
a cutter blade cooperating with the discharge control mechanism to cut the covered fiber material disposed between the discharge amount control mechanism and the cutter blade, the cutter blade being provided in an introduction flow path that delivers the plasticized material to the nozzle opening;
a control unit configured to control the plasticizing unit, the discharging unit, and the fiber introducing unit to shape a three-dimensional shaped object including the covered fiber material; and
a discharge amount control mechanism configured to control a discharge amount of the plasticized material from the nozzle opening and simultaneously cutting the covered fiber material.
