Abstract: A method of manufacturing a target component is disclosed. The method includes inputting, into a binder jetting additive manufacturing system, instructions for manufacturing a desired target component, wherein the target component includes at least one internal channel defined at least by a circuitous path including at least one bend; printing the target component via a binder jet additive manufacturing process to form a green body target component, wherein during the printing at least one port is formed that extends from an external surface of the target component to the at least one internal channel; and depowdering the at least one internal channel by accessing the at least one port formed on the green body target component.
