Original Abstract Submitted
a method for defining a plurality of irradiation vectors for an apparatus for producing a three-dimensional work piece via additive manufacturing is provided. the method comprises, for a layer of a three-dimensional work piece to be generated, defining a downskin region in the layer, and defining a set of first irradiation vectors covering the downskin region. at least one of the first irradiation vectors extends into a volume region of the layer, adjacent to the downskin region. the at least one of the first irradiation vectors has a length of 1 mm or more. the method further comprises defining a set of second irradiation vectors covering a remaining part of the volume region of the layer, assigning a first set of irradiation parameters to the set of first irradiation vectors, and assigning a second set of irradiation parameters to the set of second irradiation vectors, the second set of irradiation parameters being different from the first set.
