Abstract
An apparatus and method for additive manufacturing of components, in particular for manufacturing components for turbomachines, where the component is at least partially built up layer by layer on a substrate or a previously produced part of the component, and where layer-by-layer build-up is performed by layerwise melting of powder material using a high-energy beam and solidification of the molten powder is provided. The high-energy beam moves along a path across the powder material and produces a melting region at the front of the path. A solidification region forms subsequently in the path. In the solidification region, the temperature distribution is temporally and/or locally selected in such a way that residual compressive stresses are produced in the solidified or solidifying powder material.
