One of Hewlett Packard’s environmental goals is use of biobased plastics. It’s a goal that goes back at least six years, and so far it’s had a rocky path. Efforts to build a printer housing from plant-based went afoul a few years ago. “The first problem we had was the polylacticacid (PLA) we used came from genetically modified crops, and that never could have been used in Europe,” comments John Frey, who chairs Hewlett Packard’s environmental strategies council. “The other problem is that they weren’t really heat stable. I took one of the pilots to a meeting in downtown Houston and then left it in my car. When I came back, the whole shell had caved in around the printer mechanism.” More recently, HP came very close to shipping a notebook with two biobased parts. The parts were withdrawn at the last moment because of other engineering concerns. Frey says HP has its eye on kenaf to see if it can add required stability as a reinforcing material.
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.
