Massachusetts Institute of Technology researchers, with the help of 3D printing, have developed a material that can switch between hard and soft. The material is described in a paper in the “Macromolecular Materials and Engineering” journal. It was developed by a team led by Anette Hosoi, a professor of mechanical engineering and applied mathematics at MIT, and is made of wax and foam.

The material was created based on the needs of Defense Advanced Research Projects Agency (DARPA). The agency wanted researchers to create robots that were octopus-like in that they could squeeze through tight spaces and then expand again. After much consideration, the research team decided that the ...
