Abstract
A three-dimensional shaping apparatus includes a plasticizing section, a stage, an ejection section having a first nozzle and a second nozzle, each of which communicates with the plasticizing section, a first ejection adjusting section, a second ejection adjusting section, a moving section that relatively moves the ejection section with respect to the stage, and a control unit. The control unit performs a switching process for switching from a first state in which the ejection of the plasticized material from the first nozzle is stopped and the plasticized material is ejected from the second nozzle to a second state in which the plasticized material is ejected from the first nozzle and the second nozzle by controlling the first ejection adjusting section and the second ejection adjusting section, and an ejection amount decreasing process for decreasing the ejection amount of the plasticized material from the second nozzle by controlling the screw or the second ejection adjusting section before switching from the first state to the second state.
