I spent a month last year in the underdeveloped country of Namibia. Residents were proud to tell me that Namibia is the only country in the world that has a constitution that embraces environmental sustainability.To Namibians, it was a recognition that protection of theirs materials resources was critical to their future. Since I’ve returned to the US, however, it’s become clear that the concept of sustainability, and specifically, sustainable design, will soon become important to us as well.
One specific issue I want to focus on is use of renewable resources as a feedstock for polymers. The immediate reason isn’t really environmental, at least for design engineers. Unstable oil supplies triggered massive runups in plastics prices two years ago. Today it makes sense to study the potential of corn-based polymers for mechanical design projects. Sound crazy? At the giant plastics fair in Germany this fall (K 2007), DuPont plans to present technical data on new grades of Sorona and Hytrel that are corn based. Stay tuned.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
