The method for producing a component (11) of a turbine or a compressor, comprises layer-wisely applying a powdered component material (14) on a component platform (16) in the area of a construction- and a joining zone (20), layer-wisely and locally melting or sintering the component material by supplying energy in the area of the construction- and joining zone using an electron beam (22), layer-wisely lowering the component platform at a predetermined layer thickness, and repeating the process steps until the completion of the component. The method for producing a component (11) of a turbine or a compressor, comprises layer-wisely applying a powdered component material (14) on a component platform (16) in the area of a construction- and a joining zone (20), layer-wisely and locally melting or sintering the component material by supplying energy in the area of the construction- and joining zone using an electron beam (22), layer-wisely lowering the component platform at a predetermined layer thickness, and repeating the process steps until the completion of the component. The emitted electrons are detected by interacting the electron beam with the component material after which material information characterizing topography of the melted and/or sintered component material is determined based on the determined electrons. The electrons are detected once and/or detected during the several repetitions of process steps and/or during each repetition of process steps. In the melting or sintering step, a spatial deflection, a focusing and/or a thermal power of the electron beam are adjusted in dependent of a layer information of the component to be produced and/or in dependent of the material information by using electromagnetic and/or magnetic fields. The component material is melted and/or sintered by four electron beam. A relative position of an electron source, which is used for producing the electron beam, is adjusted opposite to the construction- and joining zone in dependent of the layer information of the component to be produced and/or in dependent of the material information. The melting or sintering step is carried out under high vacuum. The component is finely processed after its production. A surface of the component is processed by electron beam lithography and/or remelting. During the processing of the component, the emitted electrons are detected by interacting the electron beam with the component material after which the component information characterizing topography of the component is determined based on the determined electrons. The spatial deflection, focusing and/or thermal power of the electron beam are adjusted in dependent of the component information. An independent claim is included for a device for producing a component. |
