Sound waves and holograms are being used by researchers to rapidly create small 3D structures

Growing organs or tissues for medicinal purposes still seems like science fiction — and it is a very tough task. 3D-printing technology has showed considerable promise in the field of biofabrication, but the technique is excessively slow and sometimes causes tissue damage. German researchers believe they have found a solution: combining holograms and sound fields to swiftly construct matter in 3D.
