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.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
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 discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
