Traditional Manufacturing to AM

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  - I knew that General Electronics was moving to Addictive Manufacturing. Do you see this as a reliable method especially for Aircraft Engines?

Shehan you have raised a very good question , No doubt that additive manufacturing is the next booming technology but designing aircraft engine components will be risky with it

1.Type of metal created with this sort of manufacturing is still a question mark and will that metal be usefull enough to creat aircraft components

2.Secondly the material by this method is no doubt of  good quality but probably the surface will not  strong be smoothed will it be ok for crafts to fly ?

3.Will the manufacturing be strong enough to fly the palin in air ?

 

I have all these questions in my mind

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.

Chuck, most AM techniques require some post-processing, especially if it's metal parts. But that's also true of other manufacturing techniques such as injection molding and welding.

Bringing critical technologies in-house

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.

@naperlou, you bring up good points about these technologies.  It may be a slow ramp up until these parts are common, everyday items in aviation, but I believe their time is coming.

Lou, I agree with notarboca. There are several issues that must be overcome, but eventually they most likely will be overcome.

After a year or so of missteps, false starts, retractions, and postponements, inkjet office printer giant Hewlett-Packard has finally revealed just what it plans to do in 3D printing.
The company that brought you 3D-printed eyeglasses has launched both an improved clear polymer material for 3D printing optical components and a high-speed, precision, 3D-printing process for making small- and medium-sized batches in a few days.
We've found an amazing variety of robot hands & arms in medicine, space, and service robots, as well as R&D and assembly. Some are based on industrial designs modified for speed or dexterity, while others more closely emulate human movements, as well as human size and shape.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
