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 executes a first flushing operation when a distance between the shaping region and the flushing position is less than a threshold value, and executes a second flushing operation when the distance between the shaping region and the flushing position is equal to or greater than the threshold value.
