"A new method for printing 3D structures and wires from liquid metal opens up possibilities for flexible and stretchable electronic connections."

Somewhere on campus at North Carolina State University, an interesting thing happened. Researchers took a liquid metal alloy of gallium and indium at room temperature and made more than just a puddle. They made a 3D figure. They made a wire. They even made tiny letters. The remarkable occurrence was that it all held together. The researchers have spent years developing a method of 3D-printing liquid metal at room temperature.
