The National Science Foundation is funding a collaborative effort between NASA and the University of Buffalo's Department of Physics to develop a new type of shock-absorbing system that may one day protect skyscrapers, bridges, shops, and automobile bumpers from powerful impacts. Surajit Sen, an associate professor of physics at the university, designed the new shock-absorbing system that consists of a long, cone-shaped chain of spheres. The sphere positioned closest to the expected source of a shock impulse is the largest. Each subsequent sphere is slightly smaller, with the smallest sphere positioned closest to the thing needing protection from shock. As mass is reduced, the energy of the impulse is distributed, according to Sen. He envisions a structural material embedded with chains of the spheres.

Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
