The best hope for new bioplastics is to find niche applications where they fill a technical need. One great new example comes out of Cornell University, where research set up a company called Novomer to develop plastics made from carbon dioxide and cirtus fruits. Aliphatic polycarbonates (APCs) made from the process are biodegradable, biocompatible, are optically clear and provide high oxygen and water barrier. They’re also quite pricey – say $50 a pound an up.
Novomer today announced its first commercial product — NB-180, a poly(propylene carbonate) (PPC) sacrificial binder that burns cleaner, more uniformly and at lower temperatures than currently available products. Sacrificial binders provide mechanical strength to ensure uniform consistency, solidification or adhesion during manufacturing processes. Application areas are extremely broad and include advanced ceramics, microelectronics, nanotechnology, metal brazing and fuel cells. It’s aimed at assembly of micro- and nano-scale devices.
Fox Holt, product manager for Novomer says there are no plans yet to use the material as a sacrificial binder in powder injection molding – a mass market where it could really achieve some volume.
The 100-percent solar-powered Solar Impulse plane flies on a piloted, cross-country flight this summer over the US as a prelude to the longer, round-the-world flight by its successor aircraft planned for 2015.
GE Aviation expects to chop off about 25 percent of the total 3D printing time of metallic production components for its LEAP Turbofan engine, using in-process inspection. That's pretty amazing, considering how slow additive manufacturing (AM) build times usually are.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
