Beschreibung
Zusammenfassung:	An article includes a substrate and a structure of additive manufacturing material of predetermined thickness attached to the substrate, the structure of additive manufacturing material formed by providing a metal alloy powder, forming an initial layer having a preselected thickness and a preselected shape including at least one aperture, with the metal alloy powder, sequentially forming an additional layer with the metal alloy powder over the initial layer, each of additional layers having an additional preselected thickness and an additional preselected shape including an aperture corresponding to the aperture in the initial layer, and joining each of the additional layers to the initial layer or any previously joined additional layers, forming a structure having a predetermined thickness and shape, and an aperture having a predetermined profile. The article includes a passageway through the structure including the aperture and a corresponding metering hole.
