Beschreibung
Zusammenfassung:	A method for selectively irradiating a material layer in additive manufacturing of a component includes the following: providing geometric data, having a contour of a component that is to be additively manufactured, computer-based definition of an irradiation pattern for layers of the component, the irradiation pattern having at least one contour irradiation path in a layer, and wherein an irradiation of the contour irradiation path is superimposed by a pulsed irradiation in the layer for forming a predefined surface texture of the component such that melt baths, which result in the course of the production of the component from an irradiation of the contour irradiation path and such, which result from the pulsed irradiation, overlap. A corresponding additive manufacturing method, a correspondingly manufactured component and a corresponding computer program product are provided.
