3-D Printing Shapes In Liquid Metal

Researchers at North Carolina State University have developed techniques to 3-D print liquid metal at room temperature. Exploring the limits of novel 3-D printing technology, researchers at North Carolina State University have discovered a way to build microstructures out of liquid. Creating freestanding structures out of liquids is challenging, but the NC State team found an alloy of gallium and indium that's liquid at room temperature, which forms a skin in contact with air, allowing the liqui...
