3D-printing technology is developing very rapidly, and every day there are new ideas for their use. We invite you to get acquainted with the conceptual novelty raw materials to create objects which serves the molten alloy of gallium and indium, not plastic. This approach provides access to the creation of components with electrical conductivity. A team of scientists from the National Institute of North Carolina has designed a printer that creates a different structure from the droplets of liquid metal, stacking them on top of each other. Despite the high potential in the near future, this technology may be unclaimed because of the price, up to 100 times higher than the price of printing plastic.
