Abstract

An intermediate component with an internal passageway includes a solid metallic additively manufactured component with an internal passageway in a near finished shape. The component has voids greater than 0 percent but less than approximately 15 percent by volume and up to 15 percent additional material by volume in the near finished shape compared to a desired finished configuration. Also included are a ceramic core disposed within the internal passageway of the component and an outer ceramic shell mold encasing an entirety of the component, such that an entire external surface of the component is covered by the outer ceramic shell mold.
