There’s been a lot of talk about 3D printing these days. Most of the new machines use plastic powders to literally layer and print a 3-dimensional object out of thin air. 

But could 3D printing with liquid metal be the next big thing? With support of the National Science Foundation, researchers at NC State have been able to successfully do just that, printing with liquid metal at room temperature. 

To demonstrate the scope of detail possible, the researchers ‘print’ metal antennas on a bug
