3D printing with metal had been conceived of since the early 1970s and, in practice, has mostly been achieved using laser sintering (LS) although these days most people seem to be calling it laser melting, either way the process is very similar and involves fusing bits of metal powder together with the heat of a laser beam. Researchers at North Carolina State University, however, have developed a new method for printing metal and the best part is that the metal is liquid… and conductive… and it can be printed at room temperature.…
