摘要

Producing a component by a layered structure using selective laser melting, comprises for each layer fusing a powdery component material corresponding to a desired geometry of the component, using at least a laser beam and then solidifying by cooling. More layers of a shell region of the component are successively constructed with a first beam diameter of the laser beam up to a first thickness and then a layer of the first thickness of a core region remaining within the shell region, is constructed with a second beam diameter of the laser beam, which is greater than the first beam diameter. Producing a component by a layered structure using selective laser melting, comprises for each layer fusing a powdery component material corresponding to a desired geometry of the component, using at least a laser beam and then solidifying by cooling. More layers of a shell region of the component are successively constructed with a first beam diameter of the laser beam up to a first thickness and then a layer of the first thickness of a core region remaining within the shell region, is constructed with a second beam diameter of the laser beam, which is greater than the first beam diameter. The laser beam for melting the powdery component material is conducted to a given path over the shell region and the core region. The paths, on which the laser beam for melting the powdery component material is conducted over the core region, is selected in such a manner that it always reaches at least approximately perpendicular to the envelope region, during contact with the shell region.
