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.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
The 100-percent solar-powered Solar Impulse plane flies on a piloted, cross-country flight this summer over the US as a prelude to the longer, round-the-world flight by its successor aircraft planned for 2015.
GE Aviation expects to chop off about 25 percent of the total 3D printing time of metallic production components for its LEAP Turbofan engine, using in-process inspection. That's pretty amazing, considering how slow additive manufacturing (AM) build times usually are.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
