3D printing is going to change our world in many ways. Take this robotic suit made by 3D Systems. It is designed to enable paralyzed individuals to walk again. It fits onto the user’s legs and back to support the walking motion. It has battery-powered motors that drive the legs. Just think about how many folks a solution like this can help. Let’s not forget these designs can always improve and get better in the future. A truly exciting piece of work.
