Russian researchers say theyve developed a 3D printer that can print with three metals

While a number of metal 3D printers are currently on the market, many are only built to print using one type of metal material, which can be limiting for certain applications. Reportedly, however, a team of Russian researchers has developed a 3D printing technology capable of printing in three metals.
