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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
