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.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
