Three-dimensional shaped object manufacturing device

A three-dimensional shaped object manufacturing device, comprising:

• a shaping table;
• a layer forming portion configured to form a powder layer on the shaping table;
• a head configured to discharge, from a nozzle, a liquid containing a binder to a shaping region of a three-dimensional shaped object in the powder layer;
• and
• a control unit configured to control a movement of the head with respect to the shaping table and a drive of the head by applying a voltage, wherein
• the control unit is configured to:
• execute, after the liquid is discharged to the shaping region, a flushing operation of discharging the liquid from the nozzle to a flushing position different from the shaping region,
• set an applied voltage during the flushing operation higher than an applied voltage when the liquid is discharged to the shaping region, and
• change a flushing operation time at the flushing position to be longer as an interval between the shaping region and the flushing position increases according to a change in a size of a structure formed in the shaping region.
