MIT researchers are now 3D printing robots that can walk on their own

For years, 3D printing has been hailed as an emerging technology likely to transform our lives. Researchers at MIT's Computer Science and Artificial Intelligence Laboratory have taken the nascent field to a new level with the creation of 3D printed robots made of both solids and liquids. Previously, 3D printing had only been done with solid materials. Printing with both materials allows for the faster creation of complex designs, lessening the time and expense required to make robots. Inexpensive robots could make remote exploration -- or any activity where a robot is used -- more affordable, bringing broad implications for the utility of robots.
