Method for selectively irradiating a material layer, production method, and computer program product

A method for selectively irradiating a material layer in additive production, the method comprising:

• a) providing a predetermined component geometry which contains geometrical information of individual layers of a component to be additively produced,
• b) layerwise establishing an irradiation pattern in surface regions of a layer to be constructed for the production of the component, the irradiation pattern comprising irradiation vectors in each surface region, the layerwise establishment being carried out with computer aid by means of a CAM method, and
• aa) when a predefined irradiation vector length is fallen below in a first surface region, lengthening irradiation vectors in a second surface region, adjacent to the first surface region, of the layer as far as a component contour.
