Mirel bioplastic performs well as a film when annealed for two to three seconds after processing. New data on the PHB polymer was presented at the opening of the Annual Technical Conference (ANTEC) of the Society of Plastics Engineers in Boston today by Ray Krishnaswamy of Metabolix, the technology startup behind Mirel. Annealing relaxes stresses in noncrystalline chain segments, dramatically improving tear properties. Annealing equipment that could be used commercially includes IR heaters, embossing stations, or annealing roll stands. “We could build this for you for $1,000,” said to a large audience at the Fundamentals & Fellows Forum. Future research opportunities for bioplastics include controlling the rate of biodegradtion, controlling crystallization, improving thermal stability, exploring blends, and education.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
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.
