But what are the unique properties of this substance? It’s initially a liquid that is “turned into a gel after it’s already in place”. It’s flexible and electrically conductive. The substance can also store an electrical charge. To us this sounds like the characteristics of a new kind of material one could run through a 3D printer.
A material that could enable 3D printing of electrical circuit traces embedded within a 3D object. Or 3D printing an embedded battery that precisely fits an internal cavity. This could be quite important.
We don’t know how to produce this substance, but evidently it is made from “commercially available ingredients thrown into a water solution”. No doubt this discovery will be patented as it could be highly useful to not only 3D printing but also to a wide variety of 2D electrical applications.
