PROBLEM TO BE SOLVED: To produce a high-quality three-dimensional work piece by an irradiation system for irradiating layers of a raw material powder with a radiation beam.SOLUTION: A method of controlling an irradiation system 10 for irradiating layers of a raw material powder with a radiation beam 14 in order to produce a three-dimensional work piece 110 comprises the steps of defining, for at least one raw material powder layer to be irradiated, a scanning pattern comprising a plurality of irradiation sections 20, where, within each of the plurality of irradiation sections 20, a plurality of scanning vectors V is defined, in which the radiation beam 14 is scanned across the raw material powder layer according to the scanning vectors V; determining, for each of the plurality of irradiation sections 20, whether the irradiation section 20 contains a down skin area 22; and defining, for each of the plurality of irradiation sections 20, a scanning order direction S in which the scanning vectors V within the irradiation sections 20 are scanned one after another according to the determination as to whether the irradiation section 20 contains the down skin area 22.SELECTED DRAWING: Figure 2
