Abstract: The present disclosure relates to manufacturing methods. The teachings thereof may be used to manufacture a component in which the component is applied by thermal spraying with a coating jet carrying building material. For example, a method for manufacturing a component may include: producing a mold for the component layer-by-layer on a building platform using a generative process incorporating data describing the mold; building the component in the mold by filling the mold with a building material using thermal spraying with a coating jet; and removing the mold from the component.

Abstract: Various embodiments include an installation for the powder-bed-based additive manufacturing of a workpiece, the installation comprising: a process chamber; a receiving device for a powder bed in the process chamber; multiple metering devices for different types of powder, wherein the metering devices each have a cavity and a metering slit; and a plurality of storage containers, with at least one storage container for each of the multiple metering devices, wherein each storage container feeds in the respective cavity of the metering device. The metering slits are arranged radially in relation to a perpendicular center axis running through the receiving device. The receiving device and the metering devices rotate in relation to one another about the center axis.

Abstract: Various embodiments include a cooling apparatus comprising: a thermal interface for a heat source to be cooled; a thermal pipe with a first phase change medium; and a latent heat store with a second phase change medium. The first phase change medium and the second phase change medium are contained in respective volumes separated from one another. Heat of the heat source, at the thermal interface, transfers into a heat absorption zone of the thermal pipe. A melting temperature of the second phase change medium is greater than an evaporation temperature of the first phase change medium.

Abstract: A method and a device perform selective laser sintering. In the method for laser sintering, energy is applied linearly to a cross-sectional surface of the component to be produced in order to compact the powdery material. In the case of components with cross-sectional surfaces that have a curved contour, the application of energy can be guided in a line-shaped manner following the curved contour so that the contour of the workpiece that develops is continuously replicated. Advantageously, irregularities in the contour, which are caused by the raster predetermined by the laser sintering method, can thus be largely avoided. The device for laser sintering includes a powder delivery unit which can rotate about a rotational axis located in the interior of an annularly closed cross-section of the workpiece to be produced.

Abstract: A component with a self-healing surface layer, a self-healing enamel and a coating powder are disclosed. A self-healing is guaranteed by a reactive substance, which is encased in sheathed particles. Only damage to the enamel coating leads to a destruction of the coating, preferably under the influence of a catalytic material, so that the encased fluid enamel can emerge. Under the effects of UV light the fluid enamel cures and seals the crack thus occurring.
