    摘要： Machine tools combine material addition via ultrasonic object consolidation and subtractive techniques for imparting high-dimensional accuracy to a finished object. A material supply and feeder, ultrasonic horn, and feedstock cutting device are integrated with a material removal subsystem preferably including a cutting tool and an excess material removal system. Any metal, plastic or composite material suitable for ultrasonic joining may be employed as a feedstock, and these material may assume the form of tapes, sheets, wires, filaments, dots or droplets, with the feeding and material cutting components being designed for the specific feedstock employed. The cutting tool for excess material removal, may be a knife, drill/mill, grinding tool, or other tool capable of accurately cutting the external contour of a cross section of the part being built, and for removing excess feedstock remaining following the application process. The material removal could consist of a vacuum or blower system, chip auger, or other suitable apparatus. A machine disclosed as part of the preferred embodiment is able to deposit material in one step, and optionally and selectively remove it in another. Through the expeditious combination of deposition and removal, the fabrication of objects of arbitrary shape may be realized.

    摘要： A system and a method of fabricating a three-dimensional object on a substrate includes adding material layers incrementally and consolidating the layers by using ultrasonic vibrations and pressure. The layers are placed in position to shape the object by a material feeding unit, and they come in various forms, including flat sheets, segments of tape, strands of filament or single dots of material. The material may be plastic or metallic, and composition may vary discontinuously or gradually from one layer to the next, creating a region of functionally gradient material. The invention permits the construction and repair of dense objects, including fiber-reinforced composites and aerospace structures. Excess material may be removed one or more layers are bonded, including following end of the process after the final object is fabricated. The layers are fed sequentially and additively according to a layer-by-layer computer-model description of the object, which is generated by a computer-aided design/manufacturing (CAD/CAM) system. Ultrasonic welding equipment applicable to the invention preferably includes an ultrasonic generator, a transducer, a booster and a head unit or sonotrode.
