In order to overcome the limitations of the high energy beam rapid prototyping and manufacturing processes, high power ultrasonic consolidation and manufacturing technique was developed in recent years. Metal foils were bonded to-gether using very high ultrasonic energy and metal atoms were heated up by very high frequency vibration diffused from one phase surface to another to form a metallurgical solid-state combination. Compared with other rapid prototyping techniques, high power ultrasonic consolidation and manufacturing technique owns many advantages, such as low temperature, less de-formation, high consolidation speed, and environment friendly, which can be used for the intelligent manufacture of integrat-ed consolidation and machining for complex laminated metal parts. As mentioned above, it is a novel additive manufacturing 3D printing technique. This paper briefly introduces the advanced Ultrasonic Additive Manufacturing (UAM) technique and mainly reviews the achievements of the optimal process parameters of similar and dissimilar metal laminate materials( Al/Al, Cu/Cu, Ti/Al, etc. ) , then focuses on analyzing the microscopic physical metallurgy mechanism of metal ultrasonic consoli-dation and characterization techniques of interfacial properties. Based on the current study status of ultrasonic consolidation mechanism, some research aspects needed to further investigate are also pointed out in this work.
