There are a lot of possible applications for shape memory actuators, but due to cost, so far they are mostly found in high-end areas such as space transportation. There is a company in Colorado which focuses on this, and has some parts on the International Space Station (http://www.ctd-materials.com/products/emc.htm).
Also, the Europeans have had a difficult time enforcing their electronics waste regulations. Apparently, some companies have decided that the penalties for illegally exporting waste to Third World countries are cheaper than the cost of complying with the regulations, particularly since they rarely get caught and when they do get caught the penalties are not always enforced. The BBC did a story on this last year (http://www.bbc.co.uk/news/world-europe-10846395).
Until the cost of shape memory actuators goes down, and/or the cost of failing to comply with regulations goes up, I don't see this technology catching on.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
Independent science safety company Underwriters Laboratories is providing new guidance for manufacturers about how to follow the latest IEC standards for implementing safety features in programmable logic controllers.
Automakers are adding greater digital capabilities to their design and engineering activities to promote collaboration among staff and suppliers, input consumer feedback, shorten product development cycles, and meet evolving end-use needs.
