Claim 19:
20. A method of depositing an extrudate onto a substrate, the method comprising steps of:
rotating a stirring tool about an axis of rotation while urging a tool distal end of the stirring tool against the substrate, and wherein the stirring tool defines a bore, extending therethrough;
moving a die adjacent to the stirring tool along a die axis between at least a first retracted position and a first engaged position, such that the stirring tool rotates relative to the die;
moving a second die adjacent to the stirring tool along a second-die axis between at least a second retracted position and a second engaged position, such that the stirring tool rotates relative to the second die;
passing feedstock through the bore toward the tool distal end;
rotating the first die in a first direction about the die axis; and
rotating the second die in a second direction about the second-die axis, wherein the second rotational direction and the first rotational direction are opposite to each other.
