Printing frame components for quick R&D to track updates:
“Using a steel frame definitely helps, especially now with 3-D printing. Before you had to source the tubing with the correct wall thickness. Now we can print whatever you want, which makes things even better for us.”

Always wanted to buy one of those fairly cheap home units just to play with, I just dont think I have the patience lol
Heck, the AMA would never know if they would use such a frame in supercross.

Man, just a short time ago this sort of thing was just fantasy. Amazing how far it has come.
It was rather impressive.

It's a terrific article, even if a bit of a gut punch that he framed it with the life and death of his friend transplanted the same year that I was.
“'She did great,' Cohn said. 'Many heart-transplant recipients are dead in ten years.'”
“'Recently, I went to a birthday party for a guy I transplanted thirty years ago,' Frazier said. 'But those are rare, rare, rare. Only about five per cent of transplant recipients make it to thirty years.' The artificial pumps on the market are considered bridge therapies, and heart transplants “destination” therapies; but, if you live long enough, the transplants, too, are merely bridges."
It's got to be incredible now for customizing prosthetics, though.
A lot of people have been trying for years to get this stuff right , and unless you have the ability to do full 3D XRays too, on every part , you never truly know if the print is good.. that is where the cost is.
Matsura do a great 3D printer/ 5 Axis mill that adds layers then machines them back, which i was involved with proving out a few years ago, the machining allowed the shrinkage issues to be easier to rectify.
If you have seen the windscreen that Indycar added last year, you may not know it but the supporting structure of the screen is a halo system similar to what is on F1, GP2, GP3 racing cars. But the Indycar halo is a Pankl-manufactured part that is 3D printed titanium. It is printed in 3 sections, then electron-beam welded together. It's much bulkier and less elegant than the F1 halo because there is no structural area for the rearmost mounting points to the chassis, so it had to be tied into the steel roll hoop and it is much higher than it needs to be at the rear.

I've been playing with some PLA 3D-printed parts. It's really interesting stuff, both on the design side, and the printing itself. Printing/machining metal stuff in a variety of materials? It's amazing what they can do.

EDIT - I'm probably about 10 years late here.
Kinda reminds me of a modern one of these:
When I visited, there was a lot of construction going on in the back to help boost manufacturing capacity.
Between here and Motodrive, I’m guessing it’s probably closer to 20 years?
