Researchers at GE have developed a "cold spray" process that sprays metal powders at super high velocity to make or repair metal parts. Watch the video below, it is pretty damn impressive.

The resulting part should be just as strong as a cast or milled version.
How does the metal know where to bond to build the part, this some kind of physics trick at play?
Well GE developed the technology (or bought it from someone who did) so you know they're not going to tell you shit, and they have all the IP rights to anything remotely related to it well before that video hit the internet.
Knowing GE, they will probably license out the tech 5 years after ROI.
Yeah, those idiots at GE, what are they thinking spending millions of dollars on something like that when they could have been using rustoleum? /sarc
This is not paint, it's actually metal. The resulting part should be just as strong as a cast or milled version. That's the whole point of this technology - to repair worn out parts. According to the article the first application is in oil and gas drilling.
I do realize it's not "rustoleum"..... And I also realize that in the world of physics, a part made out of a solid piece of steel will always be stronger than some "cold spray" metal flake imitation... Article mentions NOTHING about strength testing... Cool idea, wrong implementation...
Sounds like the kinetic energy of each metal particle is converted to just enough thermal energy on impact to actually weld itself into place. Not too far fetched an idea, is it?

I'm sure the layman's term is 'aiming'

Haven't you figured out yet that all the geniuses inventors of world hang out here? Amazing how much research $$$ could be saved if they would only check with hardforum members first.
Thats actually pretty old tech .
Back in 80's had a machine shop and they were going around offering this tech . At time was mainly for adding X thousands of inch of a another metal on top of what you have .
You could for example have a soft shaft and then coat it with a much harder material for wear or whatever reason . You could also repair with it too , like if a bearing spun on the shaft grooving it .
It could come in handy depending on your needs .
Why do you put a space after each sentence?
