A three-dimensional shaping device includes: a discharge unit in which a plurality of nozzles are arranged along a first direction and which discharges a liquid from the nozzle toward a stage; a main moving unit that changes a relative position between the discharge unit and the stage in a second direction intersecting the first direction; and a control unit that, while changing the relative position between the discharge unit and the stage along the second direction by controlling the discharge unit and the main moving unit, repeats a processing of forming a shaping layer by discharging the liquid from the nozzle, to shape a laminated body in which the shaping layers are laminated. The control unit causes a relative position between the stage and the nozzle, from which the liquid is discharged, to be changed in the first direction when forming one of the shaping layers and when forming another layer of the shaping layers.

In a method of operating an irradiation system (10) for irradiating layers of a raw material powder with electromagnetic or particle radiation in order to produce a three-dimensional work piece (110) it is determined whether a region of a raw material powder layer (11) to be selectively irradiated with electromagnetic or particle radiation in accordance with a geometry of a corresponding layer of the work piece (110) to be produced is affected or substantially unaffected by particulate impurities. Upon selectively irradiating the region of the raw material powder layer (11) with electromagnetic or particle radiation, an energy density applied to the region of the raw material powder layer (11) by a radiation beam (14a, 14b) is controlled in such a manner that the energy density is higher in case it is determined that the region of the raw material powder layer (11) is affected by particulate impurities than in case it is determined that the region of the raw material powder layer (11) is substantially unaffected by particulate impurities.
