摘要： The invention relates to an irradiation apparatus (1) for a processing machine for manufacturing three-dimensional components by irradiating powder layers with a high-energy beam, in particular a laser beam (3), the irradiation apparatus (1) comprising: a beam forming device (14) for forming a beam profile (6, 6') for the high-energy beam, said beam profile having a length (L) along a first direction (X) perpendicularly to the beam axis (Z) of the high-energy beam as well as a width (B), which is shorter than the length (L), along a second direction (Y) perpendicularly to the beam axis (Z) of the high-energy beam; and a scanner device (15) for orienting the high-energy beam onto a position in a processing field (11) of the scanner device (15) in order for a powder layer (25) to be irradiated with the high-energy beam, the irradiation apparatus (1) being designed to change the length (L) and/or the width (B) of the beam profile (6, 6') of the high-energy beam in the processing field (11) in accordance with the position of the high-energy beam in the processing field (11). The invention also relates to a processing machine comprising an irradiation apparatus (1) of said type as well as a method for creating a layer or at least one section of a layer of a three-dimensional component.
