Method for manufacturing three-dimensional shaped object and three-dimensional shaping apparatus

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;
• and
• 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.
