Beschreibung
Zusammenfassung:	A three-dimensional shaping apparatus includes a shaping table, a layer forming section that forms a powder layer at the shaping table, a first head that ejects a liquid containing a binder to a shaping region from a first nozzle, a second head that ejects a liquid containing ceramic particles to a boundary region with respect to the shaping region from a second nozzle, and a control unit that controls movement of the first head and the second head with respect to the shaping table and driving of the first head and the second head by applying a voltage, wherein the control unit performs control so as to cause the first head to execute a first flushing operation and to cause the second head to execute a second flushing operation under a flushing condition different from that for the first flushing operation.
