this would be closer to 18 years from now, but eventually a ti driver that fades into a hardened steel race would be neat...

...This technique involves blowing multiple metal powders into a laser beam, so that the laser melts the powder and forms a small pool at the point where the laser touches the part that is being built...

NASA's JPL develops multi metal 3D printing process
sunday, 03 Aug 2014
researchers at NASA’s Jet Propulsion Laboratory say they are in development of a 3D printing technique that allows for print jobs to transition from one metal to another in a single object...
“We’re taking a standard 3-D printing process and combining the ability to change the metal powder that the part is being built with on the fly. You can constantly be changing the composition of the material.”
According to the researchers, the process is based on Laser Deposition technology, in which metal powder is injected into a high powered laser beam that melts the surface of the target object to form a small molten pool. Powder applied to this pool is absorbed and leaves a deposit as thin as 0.005 in. thick. These densely bonded layers can then be used to either build or repair metal parts.
In JPL’s technique, the build material’s composition is gradually transitioned as the print progresses. For example, the powdered build material might contain 97% titanium alloy and 3% stainless steel at the beginning of the transition. Then, in 1% increments between layers, the gradient progresses to 97%stainless steel and 3% Ti alloy by some defined point in the overall 3D printing process.
The main benefit in addition to testing the metallurgical properties of new alloy compositions is to take advantage of the differing physical properties (i.e. thermal expansion, magnetism or melting temperature) of the two or more metals in one solid component.

Using a modified version of the laser-melted powdered metal process, JPL has figured out how to make gradient metal alloys, both in a linear shape and with radial forms.

how about 3d printed parts for your body?

scanned the rib cage and printed a new one. Fucking insane. Also crazy about how biologically friendly titanium is

what I've wanted to do for a long time now, is make perfect little ti skeletons from MRIs and fossils and stuff, then anodize them. art stuff. those grateful dead dancing skeleton logos could be recreated in ti, with amazing colors...

the sternum/ribs you posted were made by csiro, who also did these
now imagine crazy rainbow anodized dinosaur skeletons.

“This technology is the only one that allows us to achieve these kinds of complex forms,” said Dubois. “We are only at the beginning, and we can still improve the product with more research on energy distribution and flow.”

Fresh AM titanium/carbon fiber bike frame designs
--- Quote ---2015.9.30
This has been a long time coming.
For what it's worth, I had the idea before either Triple Bottom Line or Bastion launched - but I'm fully aware that that doesn't buy me shit. At its core: build titanium 3D printed bike frame components, and use carbon fiber tubing for areas that are too big to practically print. This avoids the crazy crowded build chamber (and inefficient glue joints) that Renishaw/Empire's bike required, and utilizes AM for what it's good at - making customizable, low-mass parts that fit easily on a build plate.
I thought about this for a *long* time, but only this week spent some time modeling my design spaces in Inventor and poking at the lattice generation process in nTopology Element. This is still far from manufacturable, but it was great to spend a day working through how to design and customize each design space in a way that was repeatable and simple...
...I spent a *tiny* amount of time setting up lattices for each printed component in nTopology Element today. This is extremely preliminary,...

New York state to build large-scale 3D printing plant
--- Quote ---Oct 5, 2015
New York state will invest $125 million to build the world's first industrial-scale 3D printing facility as part of a private-public partnership with Norway's Norsk Titanium AS, according to sources familiar with the deal.
A groundbreaking for the plant is expected in late October or November in Plattsburgh, New York, about 160 miles north of the state capital of Albany, said the sources, who could not speak publicly before an announcement by the state.
They said the plant is slated to be fully operational by the end of 2016 when it will be able to "print" large components for aircraft manufacturers and weapons makers at much lower cost than current technologies.

Alcoa announces $60 million tech center expansion aimed at 3-D printing
--- Quote ---September 3, 2015
Alcoa announced today it is investing $60 million at its Westmoreland County technical center to expand its 3-D printing capabilities.
The aluminum and titanium producer said the new facility will focus on developing metal powders to use in 3-D printing as well as advancing the printing process and product design. The initiative will target the aerospace market as well as customers in the automotive, medical, and building and construction markets.
