1. A three-dimensional shaping apparatus shaping a three-dimensional shaping object, comprising:
a plasticizing member configured to plasticize a material to generate a shaping material;
a nozzle having a discharge port discharging the shaping material toward a table;
a movement mechanism changing a relative position between the nozzle and the table;
a discharge control mechanism configured to change an opening degree of a flow path which guides the shaping material to the discharge port to control a discharge amount of the shaping material from the discharge port;
a storage device configured to store a program; and
a processor configured to execute the program so as to:
change a relative position of the nozzle and the table at a first speed to discharge the shaping material toward the table;
set the opening degree to a first degree to discharge a first discharge amount of the shaping material from the discharge port when the relative position of the nozzle and the table is changed at the first speed;
change the relative position of the nozzle and the table at a second speed to discharge the shaping material toward the table; and
set the opening degree to a second degree to discharge a second discharge amount of the shaping material from the discharge port when the relative position of the nozzle and the table is changed at the second speed,
wherein the second speed is slower than the first speed, and the second discharge amount is smaller than the first discharge amount.
