3D printing technologies are developing very rapidly and every day new ideas appear for their use. We offer you to get acquainted with a conceptual novelty, raw materials for creating objects in which the liquid alloy of gallium and India acts, and not plastic. This approach opens up access to the creation of components with electrical conductivity. A team of scientists from the State Institute of North Carolina constructed a printer that creates various structures from drops of liquid metal, laying them on each other. Despite the high potential, in the near future such a technology may be unclaimed due to the price 100 times higher than the print price of plastic.
