Abstract
A tool head assembly for a solid state additive manufacturing apparatus includes a tool head having a material passage configured to receive a material therein. The tool head is configured to deposit the material from the material passage onto a substrate of the solid state additive manufacturing apparatus to form at least one layer of the material on the substrate. The tool head includes a shoulder configured to contact the material such that rotation of the tool head frictionally stirs the material. The tool head assembly includes a barrier configured to extend along a side surface of the at least one layer as the at least one layer is deposited onto the substrate such that the barrier is configured to constrain the material from extruding past an edge of the shoulder.
