Abstract: In the case of a method for producing a three-dimensional shaped object by means of layer-by-layer material application, a base surface for holding the three-dimensional shaped object, a liquid, flowable or powder-form first material that can solidify, a powder-form second material including thermoplastic powder particles, and a solvent are made available. From the first material, a negative mold layer having a cavity for a shaped-object layer to be produced is produced and solidified. The bottom of the cavity is charged to an electric potential having a first polarity, and the powder particles are charged to a potential having a second polarity. The powder particles are applied to a support surface that is positioned relative to the cavity in such a manner that the powder particles are transferred from the support surface into the cavity and form a shaped-object layer having a positive shape that matches the negative mold in this cavity. The shaped-object layer is sintered by means of the effect of heat.

Abstract: In a method for producing a three-dimensional mold and a three-dimensional shaped object (1) by means of layer-by-layer material application, geometry data for the shaped object (1), a support part (2) having a base surface (3) for holding the three-dimensional shaped object (1), and a first and a second material (4, 5) that can be solidified are made available. In the solidified state, the second material (5) has a greater strength than the solidified first material (4). The solidified first material (4) can dissolve in the solvent. To form a negative-shape layer (12), material portions of the flowable first material (4) are applied to the base surface (3) and/or to a solidified material layer of the three-dimensional shaped object (1) situated on this surface, in accordance with the geometry data, in such a manner that the negative-shape layer (12) has at least one cavity (13) that has a negative shape of a material layer of the shaped object (1) to be produced. The negative-shape layer (12) is solidified.

Abstract: In a method for producing a solid-body layer, an emitter array is provided. A support is rotationally positioned relative to the emitter array, about an axis of rotation, and material portions of a material that passes through the nozzles are applied to the support and solidified. The center point of the emitter farthest away from the axis of rotation has a first radial distance, and the emitter arranged closest to the axis of rotation has a second radial distance from the axis of rotation. A trigger signal is generated, which defines trigger points. A material dispensing signal is generated and temporarily stored, in each instance, for the individual emitters, as a function of geometry data and/or as a function of the position in which the emitter in question is arranged relative to the support, when the emitter is positioned at the corresponding trigger point.

Abstract: In a method for producing at least one solid-body layer on a support that can be rotated about an axis of rotation, in accordance with predetermined geometry data, an emitter array having a plurality of emitters configured as material-dispensing nozzles is provided, which nozzles are arranged in emitter columns and emitter rows. Emitter columns that are adjacent to one another in the circumferential direction of an axis of rotation are offset from one another, in the expanse direction of the emitter columns, in each instance, in such a manner that the emitters are arranged at different radial distances DA(i) from the axis of rotation. It holds true that: DA(i) DA(i+1). Print dots are assigned to the geometry data, which dots are offset from one another, in a matrix having multiple rows that run next to one another, in such a manner that it holds true that: PA(j)>PA(j+1), wherein PA(j) is the radial distance of the jth print dot Pj of the row in question from the axis of rotation.

Abstract: In a method for producing a three-dimensional mold and a three-dimensional shaped object by means of layer-by-layer material application, geometry data for the shaped object, a support part having a base surface for holding the three-dimensional shaped object, and a first and a second material that can be solidified are made available. In the solidified state, the second material includes at least one main component that can be cross-linked by means of treatment with energy, and a latent hardener that can be thermally activated, by means of which chemical cross-linking of the main component can be triggered by means of the effect of heat. To form a negative-shape layer, the first material is applied to the base surface and/or to a solidified material layer of the three-dimensional shaped object situated on this surface, in accordance with the geometry data, in such a manner that the negative-shape layer has at least one cavity that has a negative shape of a material layer of the shaped object to be produced.

Abstract: A device designed for the three-dimensional geometrical detection of an environment includes at least one inertial measurement system for provisionally calculating a trajectory of the detection device. The device is calibrated by steps of: (a) positioning and/or orienting the detection device in a position and/or orientation with respect to at least one reference point characterized by at least one predefined relative coordinate, or determining at least one relative coordinate which characterizes the position and/or the orientation of the detection device relative to at least one reference point; (b) determining at least one error variable which characterizes the deviation of the relative coordinate in accordance with step (a) from the relative coordinate(s) provisionally calculated by the inertial measurement system; and (c) if the error variable fulfills a predefined correction criterion, correcting the provisional trajectory.
