1. A three-dimensional shaping device comprising:
a stage;
a heater covering a shaping region of the stage and facing the stage;
a head configured to dispense a shaping material toward the shaping region;
a movement mechanism configured to move the stage and the head relative to each other; and
a control unit configured to control the head and the movement mechanism, wherein
the control unit is configured to perform
first shaping layer forming processing of forming a first shaping layer by controlling the head and the movement mechanism to dispense the shaping material from the head,
dispensing stop processing of stopping dispensing of the shaping material from the head by controlling the head,
determination processing of determining whether a predetermined time is elapsed since the dispensing stop processing is performed, and
second shaping layer forming processing of forming a second shaping layer on the first shaping layer by controlling the head and the movement mechanism to dispense the shaping material from the head when it is determined in the determination processing that the predetermined time is elapsed,
the control unit is configured to set the predetermined time based on information related to a shaping time of the first shaping layer and an area of the first shaping layer, and
a period of time of the predetermined time is inversely porportional to a period of time of the shaping time of the first shaping layer.
