  • Layer selective exposure in the overhang region in generative manufacturing
    Patent number: 11458573
    Abstract: Methods and systems for generative manufacturing of a three-dimensional component from a powder, wherein a layer structure model of the component to be manufactured is divided into a core region and a shell region adjacent to the core region, and wherein the shell region forms at least a portion of the surface of the three-dimensional component. Then, a layer-based irradiation process is performed in which a density of irradiated powder layers is lower in the shell region than in the core region.
    Type: Grant
