From video description:
The patented Ultrasonic Additive Manufacturing (UAM) process uses the power of sound to merge layers of metal foil. The process produces true metallurgical bonds with full density and works with a variety of metals such as aluminum, copper, stainless steel, and titanium. In combining additive and subtractive process capabilities, UAM can create deep slots, hollow, latticed, or honeycombed internal structures, and other complex geometries impossible with conventional subtractive manufacturing processes. Additionally, the solid state nature of the UAM bond allows for welding of dissimilar metals. This enables dissimilar metal cladding, production of custom metal matrix composites, and the ability to embed objects or sensors in a metal substrate. Through the use of UAM technology, customers will be able to manufacture complex parts that have unique features and attributes not possible using traditional manufacturing techniques. In addition, parts currently made with traditional operations can be made with much less waste, an increasingly important factor as more expensive, higher performance materials see broader use.
