Ultrasonic additive manufacturing (UAM) is a solid freeform fabrication process also known as Ultrasonic Consolidation (UC). It is a hybrid sheet lamination process that utilizes ultrasonic seam welding to merge metallic tapes [1,2,3] combined with computer numerically controlled (CNC) milling for dimension accuracy.
