Aviation industries are shifting from traditional manufacturing to Additive Manufacturing. Genaral Electric have also shifted to AM. GE is preparing to produce a fuel nozzle for a new aircraft engine by printing the part with lasers rather than casting and welding the metal.
AnandY, thanks for that detailed info on what GE Aviation is doing in its AM efforts.
As we mention in the article on the Lux Research 3D/AM report http://www.designnews.com/author.asp?section_id=1392&doc_id=262205 last fall GE Aviation acquired Morris Technologies http://www.geaviation.com/press/other/other_20121120.html, which was a 3D printing service bureau that produced mostly aerospace engine components.
Aviation, with its relatively low production volumes, seems to be a logical place to apply this technology. I do find it interesting, however, that the parts still require a wire EDM process after the fact.
Ann, this is an interesting trend in and it is typical of new technologies. It is also good to see it happening here. As AnandaY points out, Pratt & Whitney's biggest competitor is also starting to use this technology. Actually, GE is using a lot more ceramics and polymers in their engines, and that manufacturing is being brought in house as well.
Perhaps, as with the semiconductor industry, this will become a more standardized technology in the future. The trend in semiconductors is to seperate fabrication (fab) from design. On the other hand, in the early days of the insustry, it was fab that was the compettitive advantage. That is what allowed Intel to keep its lead for so long. On the other hand, Intel is now getting into the foundry business.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
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.
