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.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
