Additive friction stir deposition (AFSD) is a solid-state additive manufacturing process in which a rotating tool deposits a center-fed feedstock onto a substrate via plastic deformation. Tool geometry can affect the properties of the deposition. Previous studies in friction-stir welding suggest an increase in tool diameter leads to a larger contact area and thus larger deposition width. Furthermore, tool pin profile in friction-stir welding affect both the tensile properties and the size of the friction stir processed zone, as pin profile regulates material flow. Additive friction stir deposition, as opposed to friction stir welding, does not have pin profiles but can have tool protrusions. Minimal research has been done on the effect of tool geometry in additive friction stir deposition (AFSD). This research investigates that effect, specifically in the deposition of AA6061. Three different tool diameters are used, and the deposition width measured and compared normalized to input power.
