The Chevy Volt got big headlines at the Detroit Auto Show because of its electric power train. There was a tons of news in the materials as well. The materials used in a high-tech composite hood are made from regenerated plastic bottle scrap. In a proprietary GE Plastics process, bottles are reduced to their chemical constituents, which are then recovered for the manufacture of Xenoy iQ resins, which were first announced last July. As a result, there is no sacrifice in physical properties of the material, as can be the case with recycle resins. Denso, a Tier One automotive supplier, based in Kariya, Japan, has been validating applications.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
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.
