METHOD AND DEVICE FOR PRODUCING A COMPONENT
The invention relates to a method for producing a component (11), in particular a component (11) of a turbine or a compressor, wherein at least the steps of applying, in layers, at least one powder component material (14) to a component platform (16) in the area of a buildup and joining zone (20), locally fusing and/or sintering, by layer, the component material (14) by applying energy by means of at least one electron beam (22) in the area of the buildup and joining zone (20), lowering, by layer, the component platform (16) by a predefined layer thickness, and repeating the steps a) through c) until the component (11) is complete, are performed. During production, electrons (e) emitted by the interaction of the electron beams (22) and the component material (14) are captured, after which material information characterizing a topography of the fused and/or sintered component material is derived using the emitted electrons (e). Alternatively or additionally, the component material is fused and/or sintered by at least two, preferably by at least four electron beams. The invention further relates to devices (10) for producing a component (11).
