Abstract: A device (20) for unpacking a three-dimensional object (2), produced in an interchangeable container (5) and/or on a construction platform (7) by applying layers of a construction material (11) in powder form and by selective hardening thereof, from the surrounding unhardened powder (9) contains a rotating device (22) for holding the interchangeable container (5) and/or the construction platform (7), which rotating device is able to rotate the interchangeable container (5) and/or the construction platform (7) through an angle of at least 90° out of the upright position.
Abstract: A method for producing a three-dimensional object (2) by applying layers of a pulverulent construction material (11) and by selectively solidifying said material by the action of energy comprises the steps: a layer of the pulverulent construction material (11) is applied to a support (6) or to a layer of the construction material that has been previously applied and at least selectively solidified; an energy beam (14) from an energy source (13) sweeps over points on the applied layer corresponding to a cross-section of the object (2) to be produced in order to selectively solidify the pulverulent construction material (11); and a gas flow (18) is guided in a main flow direction (RG) over the applied layer during the sweep of the energy beam (14). The main flow direction (RG) of the gas flow (G) and the sweep direction (RL) of the energy beam (14) are adapted to one another at least in one region of the cross-section to be solidified.

Abstract: 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

Abstract: Treatments to improve ocular conditions such as presbyopia are provided. Structural (mechanical) weakening of the sclera is accomplished through the formation of a 3-D pattern of laser foci in the sclera resulting in an increase in the range of ocular accommodation.
Abstract: A modular system (1) for producing a three-dimensional object (2) by layerwise application and selective solidification of a pulverulent build material (13) contains a first module (30, 34-36; 40, 41) suitable for carrying out a first process used for the production of the three-dimensional object (2), and at least a second and a third module (30, 34-36; 40,41) suitable for carrying out a further process used for the production of the three-dimensional object (2). The first to third modules (30, 34-36; 40, 41) are configured so that the second or the third module, or both, can selectively and replaceably be connected to the first module in such a way that their housings are coupled to one another directly.
Abstract: A toilet. The toilet comprises an upper bowl defining a first fecal aperture, a lower bowl defining a second fecal aperture, a urine receptacle and a feces receptacle. The upper bowl defines a urine aperture. A raised barrier extends upwardly around a periphery of the second fecal aperture. When a diverter panel is closed urine flows from the upper bowl through the urine aperture into the urine receptacle or urine flows through the first fecal aperture, strikes an upper surface of the diverter panel, and through an opening between a lower surface of the upper bowl and the upper surface of the diverter panel into the urine receptacle. In a third path when the diverter panel is opened urine flows through the urine aperture into the urine receptacle, the raised barrier prevents urine flow into the feces receptacle through the second fecal aperture.
Abstract: A device for the making of a three-dimensional object (3) by means of layer by layer consolidation of a powderlike construction material (11) by electromagnetic radiation or particle beam has a height-adjustable carrier (2), on which the object (3) is built, and whose horizontal dimension defines a construction field (5). Furthermore, an irradiation device (6, 9) is present for directing the radiation onto regions of an applied layer of the construction material within the construction field (5) corresponding to an object cross section (30). A control unit (10) controls the irradiation device (6, 9) such that the powder particles of the construction material (11) are bonded together at the sites where the radiation impinges on the construction material.
