THREE-DIMENSIONAL OBJECT FORMING DEVICE AND THREE-DIMENSIONAL OBJECT FORMING METHOD

摘要

A three-dimensional object forming device, which forms a three-dimensional object by an additive manufacturing method, is provided. The three-dimensional object forming device includes: a head unit, including a plurality of nozzle rows that discharge ink droplets in an ink jet scheme; and a main scanning drive unit that causes the head unit to perform a main scanning operation, wherein each of the plurality of nozzle rows is a row along which the plurality of nozzles are aligned in a nozzle row direction that intersects the main scanning direction, and the plurality of nozzle rows are arranged along the main scanning direction so that at least some of their positions in a perpendicular direction that intersects perpendicularly with the main scanning direction overlap each other, and in the perpendicular direction, respective positions of the nozzles in each nozzle row differ from respective positions of the nozzles in other nozzle rows.
