|Abstract:||Rapid Prototyping methods are often based on additive manufacturing strategies. Depending on the application, it can also be considered the use of a removal manufacturing rapid prototyping methodology. In this paper the authors investigate the possibility of using the ultrasound technology for the shaping of materials that can be considered as a final object, or as a rapid manufactured mold for the creation of prototypes. In this case, free-form objects can be manufactured starting from foam like materials, and model the foam through the use of a ultrasonic horn thus shaping the desired features. The authors tested the possibility of implementing the technology onto automated systems, allowing considering the use of this system on automated manufacturing lines. Geometrical deviations from the 3D model are measured and material morphology before and after machining is analyzed.|
