Abstract
A plasticized material supply device includes: a nozzle configured to discharge a plasticized material toward a stage; a first flow path through which a first plasticized material flows; a second flow path through which a second plasticized material flows; a third flow path through which the plasticized material flows; a flow rate adjusting mechanism provided at a junction of the first flow path, the second flow path, and the third flow path, and configured to adjust a discharge amount of the plasticized material from the nozzle; and a control unit configured to control the flow rate adjusting mechanism. The flow rate adjusting mechanism includes a butterfly valve formed by processing a part of a drive shaft disposed along a direction intersecting a direction in which the third flow path extends, and a drive motor configured to rotate the butterfly valve by rotating the drive shaft.
