ABSTRACT

A friction stir additive manufacturing system is provided. In one aspect, the
system includes a spindle configured to rotate about a central axis, and a
housing configured to receive at least a portion of the spindle, the housing
configured to remain stationary relative to the spindle. The housing includes
a wire inlet extending between an exterior surface of the housing and an
interior surface of the housing, and a track extending from the wire inlet and
partially around a circumference of an interior surface of the housing. The
system also includes a feeding system configured to receive a wire from a
roller and feed the wire through the wire inlet and into the track of the
housing.
