Abstract
A three-dimensional shaping apparatus includes a plasticizing portion plasticizing 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 provided in a flow path which connects the plasticizing portion to the nozzle and controlling a discharge amount of the shaping material from the nozzle, and a control portion controlling the plasticizing portion, the movement mechanism, and the discharge control mechanism to shape the three-dimensional shaping object. The control portion controls the discharge control mechanism so that when a relative movement speed between the nozzle and the table is a first speed, the discharge amount of the shaping material is set to a first discharge amount, and when the relative movement speed between the nozzle and the table is a second speed which is slower than the first speed, the discharge amount of the shaping material is set to a second discharge amount which is smaller than the first discharge amount.
