Abstract

See full text

A method of ultrasonic additive manufacturing comprising using ultrasonic additive manufacturing to build a solid metal object through ultrasonically welding successive layers of thin metal foil into a three-dimensional shape; machining internal features into the solid metal object, wherein the internal features include voids, chambers, cavities, channels, or conduits; depositing a sacrificial support material in the internal features, wherein the sacrificial support material includes at least one water-soluble solid, and at least one water-soluble binding agent; curing the sacrificial support material at a predetermined temperature for a predetermined period of time within the internal features; using ultrasonic additive manufacturing to deposit additional successive layers of metal on top of the sacrificial material and solid metal object to complete the solid metal object; and introducing a solution containing water into the internal features to dissolve and remove the sacrificial support material therefrom.
