Abstract: A sealing assembly (23) for a turbomachine (1) having a seal carrier (24) and a seal structure (30) configured on the seal carrier (24), the seal structure (30) having additively built-up projections (32) that extend in each case away from the seal carrier (24) to a free end (32.1), the projections (32) being constructed in each case to have a varying cross-sectional profile, namely a particular projection (32) in a section (33) that is distal to the seal carrier (24) having a smaller thickness (34) at the free end (32.1) than in a section (35) that is proximal to the seal carrier (24).

Abstract: A layer-by-layer manufacturing method for the additive production of a region of a component, in particular of a turbomachine. The layer-by-layer manufacturing method includes: a) depositing a powder layer of a material onto a buildup and joining zone of a lowerable build platform; b) locally solidifying the material to form a component layer by selectively irradiating the material using an energy beam in accordance with a predetermined exposure strategy; c) lowering the build platform layer-by-layer by a specified layer thickness; and d) repeating the steps a) through c) until completion of the component region. Following at least one of the steps a) through c), a monitoring system ascertains and evaluates a result of the respective step; at least one intermediate correction step e) is executed for improving the ascertained result when the evaluation reveals an unacceptable deviation from a result specified for the respective step. Also, a corresponding layer-by-layer manufacturing apparatus.
