    摘要： A measuring system (40) serves for equipping or retrofitting a device (1) for manufacturing a three-dimensional object (2) by selective layerwise solidification of a building material (15). The device (1) includes an irradiator (18) for selectively irradiating a layer of the building material (15) applied in a working plane (7) of the device (1) at locations corresponding to a cross-section of the object (2) to be manufactured for solidifying the irradiated locations. The irradiator (18) comprises at least two irradiation units (31), preferably laser arrays, and each irradiation unit (31) can be projected onto a pixel in the working plane (7) and can be at least switched on and off. The measuring system (40) includes at least one camera (41) for determining and evaluating the radiation (19) emitted by the irradiator (18) and/or the position and/or orientation of the irradiation unit(s) (31) in absolute and/or relative to one another, and at least one distance sensor (42) for detecting an extension in a direction (z) perpendicular to the working plane (7).

    摘要： A method for automatically calibrating a device for generatively producing a three-dimensional object (8) comprises the following steps: irradiating an applied layer of a material (3) or a target by means of a first scanner (14) in order to produce a first test pattern (33) in the material (3) or the target; irradiating the applied layer of the material (3) or the target by means of a second scanner (15) in order to produce a second test pattern (34) in the material (3) or the target; detecting the first and second test patterns (33, 34) by means of a camera (24) and assigning the first and second test patterns (33, 34) to the first and second scanners (14, 15), respectively; comparing the first and/or the second test pattern (33, 34) with a reference pattern and/or comparing the first and second test patterns (33, 34) with one another; determining a first deviation of the first test pattern (33) from the reference pattern and/or a second deviation of the second test pattern (34) from the reference pattern and/or a relative deviation between the first test pattern (33) and the second test pattern (34); and calibrating the first and/or the second scanner (14, 15) in such a way that the first and/or the second deviation from the reference pattern and/or the relative deviation between the first test pattern (33) and the second test pattern (34) falls below a setpoint value.

    摘要： The invention describes a laser printing system (100) for illuminating an object moving relative to a laser module of the laser printing system (100) in a working plane (180), the laser module comprising at least two laser arrays of semiconductor lasers and at least one optical element, wherein the optical element is adapted to image laser light emitted by the laser arrays, such that laser light of semiconductor lasers of one laser array is imaged to one pixel in the working plane of the laser printing system, and wherein the laser printing system is a 3D printing system for additive manufacturing and wherein two, three, four or a multitude of laser modules (201, 202) are provided, which are arranged in columns (c1, c2) perpendicular to a direction of movement (250) of the object in the working plane (180), and wherein the columns are staggered with respect to each other such that a first laser module (201) of a first column of laser modules (c1) is adapted to illuminate a first area (y1) of the object and a second laser module (202) of a second column (c2) of laser modules is adapted to illuminate a second area (y2) of the object, wherein the first area (y1) is adjacent to the second area (y2) such that continuous illumination of the object is enabled.
