UK-based researchers have developed a new technique that uses soundwaves to precisely control the dispersion of droplets, something that could fundamentally transform printing.

Known as ‘sonolithography’, the technology is the work of scientists at the Universities of Bath and Bristol. It uses commercially available transducers and electronics in combination with computer algorithms to manipulate ultrasonic acoustic fields, laying down precise and repeatable patterns of microscopic aerosol droplets on a substrate.
“The power of ultrasound has already been shown to levitate small particles,” said Professor Mike Fraser from Bath’s Department of Computer Science.
