Scientists from the institute network of the Max Planck Society published article in which reported on the development of rapid 3D printing technology using ultrasonic waves. Space emitters assemble a model in the form of a hologram in a liquid medium from the working material in a matter of seconds. The technology can be used in medicine to print organs from living cells – it is non-contact and therefore sterile.
The most difficult thing in creating acoustic holograms is calculating the work of spatial emitters. According to scientists, creating each model requires a lot of computational resources. Fortunately, calculations are no longer necessary for later model constructions (3D printing). They are only created once if nothing else needs to be changed in the model.
The printing process looks like a collection of particles of matter suspended in a liquid – the model magically appears in the volume of a turbid liquid. Such printing is useful for rapid prototyping in manufacturing or medicine, where printing is accompanied by damage to biological tissues by the usual method of layering the working substance.
In their experiments, the scientists collected 3D models of living mouse myoblast cells, giving hope over time to develop full-fledged printing technology for living organs so they don’t fall apart after the sound pressure is removed.
