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.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
The upcoming MD&M West and co-located shows in Anaheim next month will be host to a huge variety of technologies and special events like the Golden Mousetrap Awards. Here are five reasons for medtech professionals to attend.
Many of the new 3D printers and printing technologies in this slideshow are breaking some boundaries, whether it's build speed, new material types, density and quality of 3D-printed circuit board layers, or build volume in a hybrid printer. We also give some recent market statistics.
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.
