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 an area of the shaping region is equal to or greater than the threshold value, and executes a second flushing operation when the area of the shaping region is less than the threshold value.
Claims8
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 is configured to
- control the head to execute a first flushing operation when an area of the shaping region is equal to or greater than the threshold value, and
- control the head to execute a second flushing operation under a flushing condition different from that of the first flushing operation when the area of the shaping region is less than the threshold value.
