Direct sound printing is a potential game-changer in 3D printing

Researchers describe a new platform technology called direct sound printing (DSP), which uses soundwaves to produce new objects. The paper explains show how focused ultrasound waves can be used to create sonochemical reactions in minuscule cavitation regions. Extremes of temperature and pressure lasting trillionths of a second can generate pre-designed complex geometries that cannot be made with existing techniques.
