Just saw this a couple of days ago Meextr; its hard to keep up with the pace of change.And i heard an interview re robots taking over all the mundane jobs and many others too, soon including automated taxis and trucks and cars!. Even heard of a sports result article on a game of baseball (i think) written by a bot and a musical score for a show at westend that was written by a bot; hell they can be creative too
3-D printed titanium to shave millions in Boeing Dreamliner costs

Boeing Co hired Norsk Titanium AS to print the first structural titanium parts for its 787 Dreamliner, the Norwegian 3-D printing company said on Monday, paving the way to cost savings of $2 million to $3 million for each plane.
The contract is a major step in Boeing's effort to cut the cost of its barely profitable 787 and a sign of growing industrial acceptance of the durability of 3-D printed metal parts, allowing them to replace pieces made with more expensive traditional manufacturing in demanding aerospace applications.
Strong, lightweight titanium alloy is seven times more costly than aluminum, and accounts for about $17 million of the cost of a $265 million Dreamliner, industry sources say.
Boeing has been trying to reduce titanium costs on the 787, which requires more of the metal than other models because of its carbon-fiber composite fuselage and wings. Titanium also is used extensively on Airbus Group SE's rival A350 jet.
"This means $2 million to $3 million in savings for each Dreamliner, at least," starting in 2018 when many more parts are being printed, Chip Yates, Norsk Titanium's vice president of marketing, said in a telephone interview.
Boeing declined to comment on the estimate but said Norsk's technology would help reduce costs.
The aircraft maker in February said it had hired privately held Oxford Performance Materials to print plastic parts for its Starliner spacecraft.
Norsk worked with Boeing for more than a year to design four 787 parts and obtain Federal Aviation Administration certification for them, Yates said.
Norsk expects the U.S. regulatory agency will approve the material properties and production process for the parts later this year, which would "open up the floodgates" and allow Norsk to print thousands of different parts for each Dreamliner, without each part requiring separate FAA approval, Yates said.
"You're talking about tons, literally," on the 787 that would be printed instead of made with traditional, expensive forging and machining, he said.
General Electric Co is already printing metal fuel nozzles for a line of new aircraft engines. But Norsk and Boeing said the titanium parts are the first printed structural components designed to bear the stress of an airframe in flight.
Norsk said that initially it will print in Norway, but is building up a 67,000-square-foot (6,220-square-meter) facility in Plattsburgh in upstate New York, where it aims to have nine printers running by year-end.

Thanks for that insight guys. I just imagined 3D printers manufacturing out of plastics.

Most of ROCKET LABS space rocket motor componentry is made using 3D printing. No machining required, this is why their satellite launches will cost significantly less than NASA.

What an amazing NZ success story Rocket Labs is. Hasn't heard of then until I saw their story at MOTAT.

Hi QOH, is your user name from the old "Q" code used in the Morse code days?

Plastics, metal, ceramic, all the way through to biological tissue.
The technology has been evolving since the early 1980's.

Nice find.
Boeing have been working on this for several years and it's good to see this finally coming to fruition.
The gas turbine nozzles mentioned in the article that GE produce are a relatively complicated shape, thin, required to withstand high temperatures and are consequently difficult to machine conventionally. The parts outlined above - which still have yet to be formally publicly identified - represent quite a step change. The devil of course will be in the detail of Boeing's definition of structural and load bearing, which at this point is likely to be very minor.

Looks like Air NZ is the number one business in Aussie...
