Abstract

A method for producing a component by the successive solidification of individual layers of powdered, granular or liquid material by irradiation with laser radiation using a laser, each layer being divided into an inner region and an edge region with an edge region surface, and, for each layer, after irradiation with the laser, at least the edge region surface of the edge region of the layer being irradiated with an ultrashort pulse laser. An optical irradiation device produces a component by successive solidification of individual layers of powdered, granular or liquid material.
