Detroit To Get $140 Million Metals Manufacturing Institute
--- Quote ---February 23, 2014
President Barack Obama Tuesday will announce that the Detroit area is getting a $148 million Department of Defense advanced manufacturing institute concentrating on lightweight and modern metals manufacturing.
...
The intent is to make the U.S. more competitive by expanding domestic markets for products made with lightweight and modern metals such as automobiles, wind turbines, medical devices, engines, commercial aircraft, and Department of Defense systems and vehicles. It
will also lead to significant reductions in manufacturing and energy costs.

In one of his state of the union speeches towards the end of 2013, he hinted at this stuff...

--- Quote ---Last year, we created our first manufacturing innovation institute in Youngstown, Ohio. A once-shuttered warehouse is now a state-of-the art lab where new workers are mastering the 3-D printing that has the potential to revolutionize the way we make almost everything. There’s no reason this can’t happen in other towns.
So tonight, I’m announcing the launch of three more of these manufacturing hubs, where businesses will partner with the Departments of Defense and Energy to turn regions left behind by globalization into global centers of high-tech jobs.

Fuck, I wish I knew how to do stock market stuff.
George, or any other smart people; Could you spend a few minutes looking into this "metalysis" stuff and tell me whether or not it's complete bunk?

Funny I'd see this now, after just looking at this yesterday

The 3D printed titanium rails are designed with Airbus. The wall thickness is just a millimetre and they weigh a third of the amount of a standard titanium rail
This is the rail straight out of the 3D printer. It's smoothed and finished after printing, with the logos polished to a mirror finish
The hyper-Pins are designed to interlock into the base of the saddle. This piece locks into the nose
The whole rail is designed to work like a leaf spring, adding comfort where you need it
This piece locks into the rear of the base
The rails locate into the base before being sonically bonded
The carbon base has slots to take the Airbus-designed 3D printed titanium rails
"Once they've been sonically bonded it takes 2 tonnes of force to separate them"
.....
Now, Charge founder Nick Larsen has developed a new brand called Fabric, in collaboration with aerospace giant Airbus, which will produce saddles with 3D-printed titanium rails and whisper-thin carbon shells. Fabric will create saddles for bike brands such as Cannondale, Larsen said.
...
3D printed rails, sonic bonds and 'hyper-pin' technology
Charge Bikes started using 3D-printing technology on the rear dropouts of its titanium cyclocross frames, working in partnership with Airbus. So when when looking at creating the rails for Fabric's flagship ALM (additive layer manufacturing) saddle, Larsen went back to Airbus. The hollow rail is shaped to act as a leaf-spring, with wall thicknesses of just 1mm, except for at the reinforced clamp section. The design weighs a third of the ti rails on the Charge knife saddle.
Traditionally, saddle makers use glue and/or bolts to attach rails to a saddle's base. With Fabric, there is another Airbus technology: the 'hyper-pin' connection. Where a standard saddle would have rails inserted into the shell, Fabric uses a series of 3D-printed pins that interlock into the shell. These are then sonically bonded to the carbon shell, which is only 1mm thick. This method of construction is used by Airbus in some of its aeronautical applications, Larsen said, so that with just eight pins interlocked, the saddle junction is able to withstand a whopping two tons of force.
"Airbus must take the credit for the carbon technology within the saddles," Larsen said. "It's something we just haven't seen in bikes ever. We've tested the rails and base and they've been bent under testing to 90 degrees and still didn't fail. That should mean the Fabric saddle should take the worst of impacts and still be fine to use."

I want to see a whole pan printed in ti - pivotal or tripod - something with a flatland shape to it, with big soft/contoured holes like a mix of these...

shaped like a khe watanabe or old gt seats... just think of the sparks and finger cuts
I also want to see what they've actually done with stuff they were talking about two years ago
G:
^^^ That is all really cool, but... saddles? Seriously? I just dont get why they are so crazily expensive and why there would be any need to get more weight off them. Surely comfort and efficiency are going to be way more important in a seat? I can easily imagine a road rider losing 1 or 2 % of their effort to seat movement, or becoming fatigued earlier because of discomfort, surely that is the main design criteria?
