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.

The invention relates to a sealing assembly for a fluid kinetic machine, in particular for an aircraft engine, for sealing a radial gap between a rotor and a stator, including at least one sealing support for retaining and/or fixing at least one sealing element, wherein the sealing support includes a first and a second radial web extending in a radial extension direction as well as an axial web extending in an axial extension direction, firmly bonded to the radial webs, and the radial webs form a receptacle for receiving an element of the stator. Therein, the radial webs are formed as sheet elements formed elongated in radial direction, wherein a radially interior end of the radial webs is respectively firmly bonded, in particular welded, to a radially exterior surface of the axial web.
