  • Patent number: 12202199
    Abstract: A three-dimensional shaping apparatus includes an ejecting section configured to eject a shaping material from a nozzle, a stage on which the shaping material is stacked, a driving section configured to change relative positions of the ejecting section and the stage, a cleaning mechanism including a brush and a blade, and a control section. The control section causes, in cleaning processing, the nozzle to reciprocate to traverse the cleaning mechanism a plurality of times to execute a cleaning operation for bringing at least one of the brush and the blade and the nozzle to come into contact. The control section causes, in the cleaning operation, the nozzle to reciprocate to come into contact with the brush or the blade in different positions of the brush or the blade. Temperature of the nozzle in the cleaning operation is lower than temperature of the nozzle at a stacking time of layers.
