Abstract: An additive manufacturing system may include a build platform configured to receive a particulate, a particulate dispenser configured to deposit the particulate onto said build platform, a consolidation device configured to consolidate at least a portion of the particulate to form a component, a first actuator assembly configured to rotate said build platform about a rotation axis at a first speed, and a second actuator assembly configured to rotate said shaft about the rotation axis at a second speed different from the first speed.

Abstract: The present disclosure provides methods of forming products using one or more lasers. In at least one aspect, a method for powder bed additive manufacturing includes defining a uniform pitch raster path for a laser traveling at a predetermined rate of travel. The raster path alternates back and forth within a strip width of less than 0.5 mm such that the laser's power density level is at least 80 percent of maximum power and the predetermined rate of travel yields a travel speed in the scan width direction of not less than 1,000 mm/s. The method includes depositing a layer of powder onto a substrate and causing the laser to solidify a quantity of the powder according to the defined raster path and the laser power setting.

Abstract: In order to create a laser tool, in particular for the structuring of cylinder running surfaces, that offers the possibility of adjusting the focal position of the laser beam with high process reliability and with high repeatability, it is provided that the laser tool has a laser source for producing laser beams, a collimator for producing a parallel course of the laser beams from the laser source, which are passed through a lens that is located within a rotatable spindle, wherein an optical device for deflecting the laser beams onto a material surface is attached to an end of the spindle facing away from the laser source, wherein the collimator is movable parallel to the laser beam by means of a drive.

Abstract: A laser tool, in particular for the structuring of cylinder running surfaces, that offers the possibility of guiding the laser beam of the laser tool with high process reliability, it is provided that the laser tool has a laser source for producing laser beams that are passed through a lens tube located in a hollow shaft, wherein a lens through which the laser beams are passed is attached to the lens tube, wherein the hollow shaft is designed to be rotatable as a hollow-shaft motor, wherein a spindle, to which is attached an optical device for deflecting the laser beam onto a workpiece surface, is attached to the hollow shaft, wherein the hollow shaft is rotatable independently of the lens.

Abstract: An apparatus for preparing food having a heating device with hot plate, a filter device and a cover device, which is in operative connection with the filter device and has an upper side, an underside and side surfaces. The cover device, on the underside, has at least one entry opening of a flow channel for exhaust air, the flow channel being arranged in the interior of the cover device. The flow channel, on a first side surface, has an exit opening, wherein the exit opening can be positioned such that the exhaust air can flow via the exit opening into an entry opening of the filter device.
