Abstract: A device for selective laser melting of a near-? Ti alloy includes a coating device for applying layers of the near-? Ti alloy on a substrate panel in a layer arrangement. The layers are arranged on top of one another. The device further includes a laser beam source for providing a laser beam for melting at least parts of the layers, and a heating unit configured to heat an uppermost layer of the layer arrangement in a direction from the substrate panel to the layer arrangement, after application of the uppermost layer and before irradiation of the uppermost layer with the laser beam, to a temperature in a temperature range of 250° C. to 600° C.

Abstract: Discloses are a method and apparatus for the additive manufacture of components by applying layers of powder material on a substrate or a previously produced part of a component and at least partial fusing of the powder material in the powder layer in line with the component cross-section contour along the powder layer and to an underlying solid material of the component or substrate for the purpose of building up several solid layers one on top of the other. Following fusion of the powder material the solid layer just generated is cleaned of powder material and, prior to deposition of the next solid layer, the edge of the solid layer is post-processed by softening the fusion-bonded material.
