Abstract
A method of additive manufacturing a structure having integrated passages is provided. In one aspect, the method includes forming first and second parts, each part having a near net shape. The first and second parts are formed by moving a friction stir tool configured to deposit a filler material. An inner surface of each part can be machined to form a generally smooth surface. The first and the second parts are joined to form a structure. The structure is machined to form a generally smooth outer surface. The method includes machining a plurality of grooves extending into the generally smooth outer surface of the structure. A tube is placed into each of the plurality of grooves and a layer of material is deposited to secure the tubes within the plurality of grooves. The method can include machining the outer surface to a predetermined shape.
