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.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
