Abstract: A method of additively manufacturing an object may include defining an interlace path for a plurality of energy beams from an energy beam system based at least in part on a route-finding algorithm. The interlace path may delineate a first contour zone of a build plane assigned to a first one of the plurality of energy beams from a second contour zone of the build plane assigned to a second one of the plurality of energy beams. An exemplary method may additionally or alternatively include outputting a control command based at least in part on the interlace path. The control command may be configured to cause the energy beam system to irradiate a layer of a powder bed with the plurality of energy beams.

Abstract: A radial compressor includes a rotor, a housing, and a radial compressor impeller which is rotationally fixed to the rotor. The radial compressor impeller has a wheel disk on which rotor blades are arranged in the circumferential direction, the rotor blades have a leading edge and a trailing edge. The radial compressor includes an impeller hub in the region in front of the leading edge of the rotor blades of the radial compressor impeller, the hub is arranged on the end of the rotor and/or the wheel disk in a concentric and rotationally fixed manner. Rotor blades with leading edges and trailing edges are also arranged on the impeller hub in the circumferential direction.

Abstract: Tilting segment for a shaft bearing device, with a base body that has a slide bearing face bounded by a segment leading edge extending in axial direction, a segment trailing edge likewise extending in axial direction, and by lateral edges extending in circumferential direction between the segment leading edge and the segment trailing edge. A groove that extends in axial direction and is located nearer to the segment trailing edge than it is to the segment leading edge is incorporated in the slide bearing face.
