Abstract (en)
[origin: WO2022017670A1] The invention relates to a method for providing manufacturing instructions for the powder-bed-based additive manufacturing of a component (10). The method comprises providing first irradiation vectors (V1) for a layer (n) to be additively manufactured, which first irradiation vectors, upon appropriate irradiation by an energy beam (5), in particular a laser beam or electron beam, cause a porous structure of the layer, as well as providing the first irradiation vectors (V1) for a layer (n+1) which is to be additively manufactured and which follows the layer (n), in such a way that paths (11) of a porous structure (12) of the layer (n) and of the following layer (n+1) at least partially overlap in order to allow for a flow through the manufactured component along a build-up direction (Z). The invention also relates to a corresponding additive manufacturing method, a correspondingly manufactured component, as well as a computer program or computer program product.
