Abstract: A method for producing a vibration-damping structure combination for damping vibrations for movable masses, having a first structure and a further structure, the further structure movable within a stop surface defined by a first structure surface of the first structure. The method includes a) providing the first structure, having the first structure surface and which defines a coating surface of a coating at least in some sections; b) coating the first structure surface of the first structure with the coating, the coating surface of the coating being applied such that a cavity is formed; c) filling the cavity with the filler; d) curing the filler until the further structure having a further structure surface is formed, which lies against the coating surface; and e) removing the coating, the further structure thus being movable relative to the first structure within the stop surface defined by the first structure surface.

Abstract: The present disclosure relates to turbomachines. Teachings thereof may be embodied in a blade for a turbomachine, having an interior space which is surrounded by a wall structure which forms the surface of the blade. For example, a blade for a turbomachine may include: an interior space surrounded by a wall structure forming a surface of the blade; and openings in the wall structure. The openings may include a plurality of micro-channels each extending from the interior space to the surface. Each of the plurality of micro-channels forms a path may define a particular direction for flowing cooling gas. The plurality micro-channels may be distributed over an area region of the surface.

Abstract: A powder-bed-based, additive production method for producing a component is disclosed. Individual layers are applied by a support component onto the powder bed in which the component is produced. Each layer can be removed from a supply powder bed having the same dimensions as the powder bed, and the layer can be compressed using a compressor. High quality layers may be produced in this manner. The layers may be compressed and flat as a result of their contact to the carrier component, e.g., the support component. The quality of the component that is produced can thus also be improved.

Abstract: A component is manufactured by selective laser melting by a laser having an intensity profile set largely constant by a diffractive optical element, so that the treatment surface which has occurred as a result of this profile is melted uniformly on the surface of the component. Thermal load peaks, such as occur due to an intensity maximum of an unshaped laser, can therefore be advantageously avoided. Moreover, the treatment surface may, for example, have a square shape, so that, in the case of rectangular components, it becomes simpler to produce the corners of the cross section to be manufactured. Overall, as a result, components having improved surface quality can be produced. The system is equipped with suitable optics for generating the intensity profile described.
