    Liquid metal 3-D printer

    In a short article by Troy Wolverton published in my newspaper today, it is reported that a team of scientists at North Carolina State University have demonstrated a technique that could be used to print objects made with the material, an alloy of gallium and indium that is liquid at room temperature. Using a syringe filled with liquid metal, the team "printed" wires and small, free-standing structures composed of balls of the material. The article says that the material could be used in the not-too-distant future in semiconductors and flexible electronics. The scientists claim that the material could be used in 3-D printing. Unfortunately, the new material will cost about 100 times more than the plastics used in current commercial printers.

    The fact that it stays liquid after printing, with just a thin solid shell seems pretty limiting for practical applications. Who knows where it will lead, though. One advancement here, another there, and big jumps forward can come together.

    Now here's some more functional 3D metal printing (laser sintered metal powder): http://gizmodo.com/nasas-3d-printed-...-inf-746527818
