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.
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.
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.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
