Watch: Flying 3D Printer Could Clean Up Nuclear Waste

3D printers are taking flight, New Scientist reports. Using helicopter rotors, scientists at Imperial College London have created the world’s first flying 3D printer to carry out tasks, like removing nuclear waste, in hostile environments. It works by hovering over an object and printing polyurethane foam, an adhesive compound. Next, another drone flies in and lands on the object, becoming attached to it; the drone can then fly off, hauling the radioactive nuclear waste away.
