Three-dimensional shaping apparatus and method of manufacturing three-dimensional shaping object

A three-dimensional shaping apparatus comprising:

• a discharge head discharging a shaping material;
• a shaping stage on which the shaping material discharged from the discharge head is stacked;
• a moving positioner changing a relative position between the discharge head and the shaping stage by driving force of a motor;
• a temperature adjustment element provided in the shaping stage to adjust a temperature of the shaping stage;
• a memory configured to store a program;
• and
• a processor configured to execute the program so as to:
• cause the discharge head to discharge the shaping material on the shaping stage to complete a three-dimensional shaping object on the shaping stage while causing the moving positioner and the motor to change the relative position between the discharge head and the shaping stage;
• leave the completed three-dimensional shaping object on the shaping stage for a predetermined period of time to cure the completed three-dimensional shaping object;
• and
• cause the temperature adjustment element to heat the shaping stage so as to increase a temperature of a bottom part of the cured completed three-dimensional shaping object that contacts the shaping stage,
• wherein the shaping material includes a thermoplastic resin, and
• the increased temperature of the bottom part of the cured completed three-dimensional shaping object is higher than a glass transition point of the thermoplastic resin and lower than a melting point of the thermoplastic resin.
