Claim 20:
21. A manufacturing method for manufacturing a workpiece comprising:
dispensing a deposition material through a channel of a nozzle;
heating the deposition material inside the nozzle to melt the dispensed deposition material;
dispensing the melted deposition material to form a melt pool on a surface of the workpiece to form an additive material layer on the workpiece while moving the workpiece in a movement plane;
providing ultrasonic waves into the melt pool in a direction substantially perpendicular to the movement plane to cause cavitation within melt pool of the melted deposition material in order to wet and form bonds between the melted deposition material and the workpiece; and
continuing to move the nozzle while dispensing the deposition material to manufacture the workpiece.
