摘要： The invention relates to a method for the quality assessment of a component produced by means of an additive manufacturing method. In the course of the method, it is checked first of all whether the component violates predetermined absolute limits in order to rule out the existence of serious malfunctions in the additive manufacturing process. Subsequently, a component-dependent targeting process is determined. On the basis of this targeting process, the limits for deviations are established and deviating actual values of the component are isolated and assessed by means of various parameters.

摘要： A blade of a turbomachine is provided, including at least one cooling channel in the interior of the blade for cooling the blade with the aid of a fluid flowing through the cooling channel, the cooling channel having at least one inlet and at least one outlet, between which the cooling channel extends along its longitudinal axis, and the cooling channel being radially delimited by at least one wall, at least one displacement body being situated in the cooling channel, so that an annular or tubular gap between the displacement body and the wall of the cooling channel results in the area of the displacement body/bodies, which is available for the through-flow of the fluid, or at least two or multiple subchannels being formed in the area of the displacement body/bodies. The invention also relates to a method for manufacturing a corresponding blade.
