    This 3D Printer can Watch Itself Fabricate Objects

    Rendering shows a six-legged robot, standing against a black background, in the process of being 3D-printed. Near the back of the robot, floating black spheres are assembled and then cured by a blue UV light beaming down from above. On top, cameras point down to scan the action.
    Caption: This rendering shows a robot being built layer-by-layer using the new process. The black spheres represent the material that the printer uses. The material is then cured by UV light, represented in blue. At the top of the image are the cameras that scan the procedure and adjust accordingly.

    Computer vision enables contact-free 3D printing, letting engineers print with high-performance materials they couldn’t use before. With 3D inkjet printing systems, engineers can fabricate hybrid structures that have soft and rigid components, like robotic grippers that are strong enough to grasp heavy objects but soft enough to interact safely with humans.

    These multimaterial 3D printing systems utilize thousands of nozzles to deposit tiny droplets of resin, ...
