Abstract: The invention relates to a beam analysis device (10) for determining the axial position of the focal point (71) of an energy beam or a sample beam (70) decoupled from an energy beam, comprising a beam-shaping device (12), a detector (40), and an analysis device (45). The beam-shaping device (12) is designed to release two sub-beams (72, 73) from the sample beam (70) on a plane of the sub-beam release process (19). The cross-sections of the two sub-beams (72, 73) are defined by sub-apertures (32, 33) which are delimited from each other and which are arranged at a distance k to each other in a first lateral direction (31). The beam-shaping device (12) is designed to image the two sub-beams (72, 73) in order to form two beam spots (92, 93) on the detector and deflect at least one of the two sub-beams (72, 73) in a second lateral direction (37) which is oriented transversely to the first lateral direction (31) in order to form a distance w in the second lateral direction (37) between the two beam spots (92, 93).

Abstract: The invention relates to a method and a device for the analysis of energy beams in systems for the additive manufacture of components (70) by means of layered solidification of a construction material (55) by an energy beam (30). The invention enables a determination of position-related beam data directly with respect to the processing point during the machining process. An additive manufacturing system includes a beam deflecting device (40), a processing plane (45), and a layer applicator (60). The device according to the invention comprises a movable beam barrier (17), a movable beam sampling module (20) and a measuring device (10) with a radiation detector (12).

Abstract: In a method for producing an acoustical damping unit, a plurality of bodies, e.g. plastic balls, of predefined sizes are produced and brought together in a desired shape by a 3D printing process. The bodies are arranged such that air can flow through gaps between them, wherein the air can flow through the complete acoustical damping unit. The gaps are interconnected so that the acoustical damping unit is open-pored. An acoustical damping unit in the form of a 3-dimensional body with a desired acoustical damping can be produced by adjusting the size of the bodies, the temperature of the plastic and the speed of application of the plastic bodies.
