Abstract
A variation in a deposition amount per unit area of a plasticized material discharged from each nozzle and deposited on a stage due to a variation in a discharge amount of the plasticized material discharged from each nozzle is reduced. A three-dimensional shaping device includes: a plasticizing unit configured to generate a plasticized material by rotation of a screw; a discharge unit configured to discharge the plasticized material from a plurality of nozzles; a discharge amount adjustment unit configured to adjust a discharge amount of the plasticized material from each of the plurality of nozzles; a moving unit configured to relatively move the discharge unit with respect to a stage; and a control unit. The control unit executes, based on a discharge state of the plasticized material from the plurality of nozzles, at least one of a first control of controlling a rotation speed of the screw, a second control of controlling the discharge amount by the discharge amount adjustment unit, and a third control of controlling a relative speed of the discharge unit with respect to the stage, so as to laminate a shaping layer formed of the plasticized material on the stage.
