Abstract
A method for manufacturing an impeller of a rotary machine, the impeller including at least one vane limiting an inner channel, which is at least partly closed, the method includes successively manufactured the impeller of several material layers by a build-up process from a powder. The powder is applied in each case to a processing plane for the production of each material layer, and then a solid material layer is produced from the powder by a selective energy input, and structural orientation is determined for the impeller, according to which the impeller is built up in layers, and the structural orientation is defined by a first and a second angle, which angles describe the relative position of the impeller to the processing plane.
