Abstract
A three-dimensional object forming device, for forming a three-dimensional object by an additive manufacturing method, is provided. The three-dimensional object forming device includes: a head unit, having at least one inkjet head provided with at least one nozzle row; and a main scanning drive unit. The head unit has a plurality of nozzle rows, and forms a plurality of laminated ink layers on at least some area. Each of the nozzles in the plurality of nozzle rows discharges an ink droplet to each different position in an operation of forming one of the ink layers; and in an operation of forming at least any two ink layers, laminated successively, ink droplets are discharged in such a way that ink dots formed by the same nozzle are not stacked at the same position.
