Multi-material 3D printed Soft Robots

This video shows Multi-material 3D printed Soft Robots, which is a lot of fun stuff in one package. Researchers from the Wyss Institute at Harvard University developed a really fast way to switch materials while 3D printing and then used it to print robots that were a combination of soft and rigid parts.

Fantastic! I would love to see this used for easily dissolved support material, or circuits embedded into the bones of my robots.
