摘要： A method for manufacturing at least a metallic portion of a component: a) depositing metallic material layer by layer onto at least one building platform; b) locally fusing and/or sintering the material layer by layer by supplying energy by at least one high-energy beam in the region of a buildup and joining zone to form at least a portion of at least one component layer of the component portion and/or of the component; c) lowering the building platform layer by layer by a predefined layer thickness; and d) repeating the steps a) through c) until completion of the component portion and/or of the component. Before, during and/or after process step b), at least one further portion of the component layer is formed by locally fusing and/or sintering the material by inductive heating at a temperature or in a temperature range above the solidus temperature of the metallic material used. A system for manufacturing at least a portion of a component is also provided.

摘要： A method and apparatus for direct writing of single crystal super alloys and metals. The method including heating a substrate to a predetermined temperature below its melting point; using a laser to form a melt pool on a surface of the substrate, wherein the substrate is positioned on a base plate, and wherein the laser and the base plate are movable relative to each other, the laser being used for direct metal deposition; introducing a superalloy powder to the melt pool; and controlling the temperature of the melt pool to maintain a predetermined thermal gradient on a solid and liquid interface of the melt pool so as to form a single crystal deposit on the substrate. The apparatus configured to generally achieve the aforementioned method.

摘要： A method for layer-by-layer manufacturing of a three-dimensional metallic work piece, comprising the steps of: delivering a metallic feed material in a substantially solid state into a feed region; emitting an electron beam having one or more predetermined electrical currents; translating the electron beam through a first predetermined raster pattern frame in an x-y plane that includes: a plurality of points within the feed region sufficient so that the metallic feed material is subjected to a melting beam power density level sufficient to cause melting of the metallic feed material and formation of a molten pool deposit; and a plurality of points in a substrate region that is outside of the feed region, sufficient so that the plurality of points outside the feed region is subjected to a substrate beam power density level that is different from (e.g., lower than) the melting beam power density level; monitoring a condition of one or both of the feed region or the substrate region substantially in real time for the occurrence of any deviation from a predetermined condition; upon detecting of any deviation, translating the electron beam through at least one second predetermined raster pattern frame in the x-y plane that maintains the melting beam power density level substantially the same as the first predetermined raster pattern frame, but alters the substrate beam power density level in a manner so that the monitored condition returns to the predetermined condition; and repeating the above steps at one or more second locations for building up layer by layer, generally along a z-axis that is orthogonal to the x-y plane, a three-dimensional layered metallic work piece. The teachings herein also contemplate an apparatus that includes an electronic control device that performs any of the methods herein, as well as articles made according to such methods.
摘要翻译：一种用于逐层制造三维金属工件的方法，包括以下步骤：将基本上固态的金属进料输送到进料区; 发射具有一个或多个预定电流的电子束; 将电子束平移在xy平面中的第一预定光栅图案框架，其包括：进给区域内的多个点足够使得金属进料材料经受足以使金属进料熔化的熔融束功率密度水平材料和熔池沉积物的形成; 以及位于进料区域之外的基板区域中的多个点，足以使进料区域外的多个点经受与（例如，低于）熔融束不同的基板束功率密度水平功率密度水平; 基本上实时监视进给区域或基板区域中的一个或两个的状态，以发生与预定条件的任何偏差; 在检测到任何偏差时，将电子束平移通过xy平面中的至少一个第二预定光栅图案框架，其维持熔融光束功率密度水平与第一预定光栅图案框架基本相同，但是改变衬底光束功率密度水平以使监视条件恢复到预定条件; 并且在一个或多个第二位置重复上述步骤，用于一般地沿着与x-y平面正交的z轴一层一层地建立三维分层金属工件。本文的教导还考虑了一种装置，其包括执行本文中的任何方法的电子控制装置以及根据这些方法制造的制品。
