MIT researchers created a system that prints functional drones and robots

Researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have created a system that can build fully functional drones, robots and other electronic devices by itself. As the name suggests, LaserFactory is built around a laser cutter in a two-part setup involving a software package for designing devices and a machine that brings them to life. Users can design a device with components from a library, add circuit traces (i.e. the electrical lines on a circuit board) and make some tweaks with a 2D editor. Once you're happy with your creation, the software sends the directions to the LaserFactory hardware. Along with the laser cutter, the system includes a device that prints the circuitry and puts together components.
