Abstract

The present invention relates to a method for the generative production of components, particularly of single-crystalline or directionally-solidified components, particularly for the production of components for turbomachines, in which the component is constructed in layers on a substrate or a previously produced part of the component (), wherein a construction in layers takes place by melting of powder material in layers with a high-energy beam () and solidification of the powder melt () takes place, wherein the high-energy beam has a beam cross section () in the area of its impingement on the powder material that is altered in comparison to a circular or other symmetrical cross section and/or the beam energy is distributed non-uniformly, in particular asymmetrically or eccentrically, over the beam section.
