Forget inkjet, your next printer could be based on sound – TechRadar

In a major breakthrough, scientists at the Universities of Bath and Bristol have successfully used sound to control ink droplets and print precise patterns.
A paper on the new printing technique, named Sonolithography, has been published in Advanced Materials Technologies journal.
The power of ultrasound has already been shown to levitate small particles. We are excited to have hugely expanded the range of applications by patterning dense clouds of material in air at scale and being able to algorithmically…
