Acoustophoretic Printing

I love learning and writing here about technology that has the potential to impact our lives.

While reading an article from the LiveScience RSS feed (near the bottom of the right sidebar on this blog), an unrelated video flew past that I nearly missed. It spoke of acoustophoretic printing.

In a nutshell. The technology uses different amplitudes of sound to dislodge different sized droplets from the nozzle of a 3-D printer to achieve greater control over the droplet size. The effect varies with the different materials used, but it pretty much adds a scientific level of quantity control to measure each droplet…like the difference between a centrifugal pump and a peristaltic pump. The following video discusses, with pictures, the abstract of the a new paper (August 31, 2018) regarding it

And to demonstrate the effect using actual numbers…

Acoustophoretic printing also controls the path of the droplets, to combine them with other droplets with more consistency.

The implications of all of this, in the more scientifically precise areas of food and medicine, are profound in that it continues to expand the usefulness of 3-D printing beyond simple pre-manufacture modeling and moves 3-D printing closer to replacing traditional, more limited ways of making things on the industrial level.

Sounds wonderful!
