The present application describes a method of controlling an irradiation system (20) for use in an apparatus (10) for producing a three-dimensional work piece, the apparatus (10) comprising a plurality of irradiation units (22a, 22b) a first and a second irradiation area (18a, 18b) as well as an overlap area (26) arranged between the first and the second irradiation area (18a, 18b) is defined on a surface of a carrier (16) adapted to receive a layer of raw material powder. A first irradiation unit (22a) of the irradiation system (20) is assigned to the first irradiation area (18a) and the overlap area (26), and a second irradiation unit (22b) of the irradiation system (20) is assigned to the second irradiation area (18b) and the overlap area (26). If it is determined that a section (S) of a radiation pattern according to which radiation beams (24a, 24b) emitted by the irradiation units (22a, 22b) of the irradiation system (20) are guided over the layer of raw material powder received on the carrier (16) and/or a contour of the three-dimensional work piece to be produced extend(s) into the first and the second irradiation area (18a, 18b) defined on the surface of the carrier (16), said section of the radiation pattern and/or said contour, in a splitting region of the section of the radiation pattern and/or the contour which is located in the overlap area (26) arranged between the first and the second irradiation area (18a, 18b), is split into a first portion and a second portion. The first portion of said section of the radiation pattern and/or said contour is assigned to the first irradiation unit (22a) and the second portion of said section of the radiation pattern and/or said contour is assigned to the second irradiation unit (22b). |
