Abstract: A method that includes additively manufacturing with an additive manufacturing (AM) system a sub-component that has a locator element. Using a control system of the AM system for positioning a first location of the locator element. Selectively placing a portion of another sub-component adjacent to the locator element, based on the positioning. Then attaching the second sub-component to the first sub-component in a region, wherein the region is based on the positioning knowledge from the control system so as to make a component. A component that comprises a first sub-component that has an AM locator element; and a second sub-component attached to the first sub-component, wherein the locator element is attached to the second sub-component within the same additive manufacturing build chamber as the first sub-component.

Abstract: An electrode applied in electro-machining processes, where the electrode includes a main body portion and at least one built-in internal flushing passage for introducing a flushing liquid to a volume between the electrode and a workpiece to be machined. The electrode is made by an additive fabrication process that enables specialized flushing for enhancing waste material evacuation and incorporate special material properties like zones of high electrical conductivity and thermal resistance. The fabrication process produces materials and geometries that could not otherwise be made using conventional processing.
