Abstract
The present disclosure relates to powder-bed-based additive manufacturing methods, in which a component is produced layer by layer in a build-up process by local melting of particles in a powder bed. For example, a powder-bed-based additive manufacturing method may include: producing a component layer by layer in a build-up process by local melting of particles in a powder bed; interrupting the build-up process after a layer has been completed; post-treating a surface of the component by laser peening, wherein compressive stresses are generated at the surface of the layer that has been completed; and restarting the build-up process for producing a next layer. An installation for the powder-bed-based additive manufacturing method may include an application apparatus for an ablation medium.
