Abstract
A three-dimensional shaping apparatus includes a material melting portion melting a material to form a shaping material, a supply channel through which the shaping material flows, a rotator that is configured to rotate around a rotation axis and that has a first nozzle configured to communicate with the supply channel and a second nozzle configured to communicate with the supply channel, a flow rate regulating mechanism that is provided in the supply channel and that regulates a flow rate of the shaping material to be supplied to the first nozzle or the second nozzle, and a controller controlling the flow rate regulating mechanism and the rotator so as to eject the shaping material to a table from the first nozzle or the second nozzle, thereby shaping a three-dimensional shaped article, wherein the controller controls rotation of the rotator so as to switch between a first state where the supply channel and the first nozzle communicate with each other and a second state where the supply channel and the second nozzle communicate with each other, and in the first state, the second nozzle is located at a position more distant from the table than the first nozzle, and in the second state, the first nozzle is located at a position more distant from the table than the second nozzle.
