Abstract
A three-dimensional shaping device includes: a shaping table; a layer forming unit configured to form a powder layer on the shaping table; a head configured to eject a liquid containing a binder from a nozzle to a shaping region; and a control unit configured to control movement of the head with respect to the shaping table and driving of the head by applying a voltage. The control unit changes an execution condition of a flushing operation depending on whether an idle running time during which the head is moved without ejecting the liquid is less than a threshold value or equal to or greater than the threshold value.

A three-dimensional shaping device, comprising:
- a shaping table;
- a layer forming unit configured to form a powder layer on the shaping table;
- a head configured to eject a liquid containing a binder from a nozzle to a shaping region of a three-dimensional shaped object on the powder layer;
- and
- a control unit configured to control movement of the head with respect to the shaping table and driving of the head by applying a voltage, and to control the head to execute a flushing operation at a flushing position which is a position different from the shaping region, wherein
- the control unit changes an execution condition of the flushing operation depending on whether an idle running time during which the head is moved without ejecting the liquid is less than a threshold value or equal to or greater than the threshold value.
