Abstract (en)
[origin: WO2011050765A1] The invention relates to a method for producing a component of a turbomachine, especially a hollow structural part of a turbine or a compressor. The method is characterized by the following steps: a) layer-by-layer deposition of at least one powder component material (16) onto a component platform in the region of a buildup and joining zone (14), the deposition taking place in accordance with the layer information of the component (10) to be produced; b) local layer-by-layer fusion or sintering of the component material (16) by means of energy supplied in the region of the buildup and joining zone (14), the buildup and joining zone (14) being heated to a temperature just below the melting point of the component material (16); c) layer-by-layer lowering of the component platform by a predefined layer thickness; and d) repetition of steps a) to c) until the component (10) is finished. The invention further relates to a device (30) for producing a component (10) of a turbomachine, especially a hollow structural part of a turbine or a compressor.
