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.
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.
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.
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.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
