Abstract: An apparatus and method for removing excess material, preferably a powder, from a cavity of a component, wherein the apparatus includes: a platform for retaining the component, preferably an additively manufactured component, a drive mechanism being coupled to the platform, wherein the drive mechanism is configured to rotate the component being retained by the platform independently around two orthogonal spatial directions and each with an unlimited angular deflection, an actuator for mechanically actuating the platform during a removal of the excess material, and a housing, defining a working space in which the excess material can be removed from the cavity, wherein the housing seals the working space against an environment, and wherein any electrical components for the drive mechanism are arranged out of the working space.

Abstract: A powder bed fusion system for a multi-material production of an object layer-by-layer using thermal energy to induce fusion to the materials. The system includes a manufacturing surface being a sub-area of a recoating surface where the object is formed, material depositing recoater that deposits the materials in a layer on the surface, an energy source that selectively directs energy to the materials, first and second material supply containers to store first and second materials. A first material overflow container at the side of the second supply container, having a first shutter separating the first material over-flow container from the recoating surface, with an open and closed position. A second material overflow container at the side of the first supply container, having a second shutter separating the second material overflow container from the recoating surface, with an open and closed position. The first and shutters are independently operable.

Abstract: A method for producing a three-dimensional component having one or more cavities by powder-based additive manufacturing, such as selective laser melting or electron beam melting, using an additive manufacturing machine. The method includes creating 3D-CAD-data of the component to be produced using a computer-aided design method; b) identifying the cavities of the component in the 3D-CAD-data and verifying, that each cavity has at least one outlet passage connecting the cavity to the outer environment of the component, wherein, if there is no such outlet passage, it is created within the 3D-CAD-data; c) producing the component on a construction platform of the additive manufacturing machine on the basis of the 3D-CAD-data; d) removing powder present within the cavities and within the outlet passages through the outlet passages and e) heat-treating the construction platform and the component arranged thereon in a heat treatment oven.
