Patent ID: 11014298

Abstract:
A three-dimensional shaping apparatus includes a supply channel through which a shaping material supplied from a melting section flows, a first branch channel and a second branch channel, a coupling section configured to couple the supply channel and the first branch channel and the second branch channel, a first nozzle communicating with the first branch channel, a second nozzle communicating with the second branch channel and having a nozzle diameter larger than a nozzle diameter of the first nozzle, a valve mechanism provided in the coupling section, and a control section. When switching a state in which the supply channel and the first branch channel communicate and the supply channel and the second branch channel are cut off to a state in which the supply channel and the second branch channel communicate and the supply channel and the first branch channel are cut off, prior to ejection of the shaping material from the second nozzle to a shaping region, the control section discharges the shaping material remaining in the second branch channel from the second nozzle to a region different from the shaping region.
