The team created a new apparatus with off-the-shelf hardware: a couple of aluminum rods and tripods. The twist in their technique is a 3D vision system, a Microsoft Kinect, that maps the location of the object before immersion. It gives them the ability to virtually simulate the distortion so they can use that calculation to print a precise image. In their demo video, when one of the rods slowly and consistently dips the object into the tub, the film in the water wraps around it and aligns perfectly. This method accounts for complex textures so you can immerse the object multiples times at different angles for life-like replicas.
