A method for manufacturing an impeller of a rotary machine is put forward, 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. Furthermore, an impeller produced according to such a method is put forward. 提出了种用于制造旋转式机械的叶轮的方法，所述叶轮包括至少个叶片(3)，所述至少个叶片(3)限制了至少部分封闭的内沟槽(7)，在所述方法中，叶轮从粉末借助于堆积过程由若干个材料层相继地制成，其中，所述粉末在每种情况下被施加到用于每个材料层的生产的加工平面，并且然后通过选择性能量输入从所述粉末生产实心材料层，并且其中，为所述叶轮确定结构取向，所述叶轮根据所述结构取向以层的形式
