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.
