NEC is developing shape memory plastics made of plant-based materials for use as wearable electronic products. The new plastic will lose it shape when heated with something as simple as a hair dryer and then will resume its original shape when heated again. The plan is to use the materials for mobile phones that users can form into unique shapes and wear around their wastes. They can be heated again to resume their original shape. NEC also plans to use the shape memory plastics in PCs. If a housing is deformed by heat, it could be returned to its original shape through application of heat. NEC commented that there were efforts to introduce oil-based shape memory plastics to these applications before but they were abandoned because the plastics were not recyclable. NEC first reported its work on bioplastc shape memory products in 2005, and updated Design News this month.
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
