Let me know what you need. Freepmail me an email address. Can’t guarantee speed, but we are all in it long haul anyway with classics. I have a 48 Chevy pickup, 57 Bel Air, 67 Camaro.

Right now you can do very short runs with 3D, because of cost and speed. But the key now is being able to prototype molds quickly. Long term, who knows how fast or cheap it will get.

Injection molding plastics or die cast metals would be hard to beat for speed or price. BUT you have to figure transportation costs and flexibility in too. EXPENSIVE to modify injection molds.

It is only $50K, from Australia, and has a chamber 8"x8"x10", a pretty useful size.

Sure is! Beautiful printer. I can think of a number of things I'd like to try to make with that thing. The price tho... OUCH!

OTOH, if you can afford a nice car, you could afford it, and make all kinds of gifts for your friends.

If it can be made to print martensitic steel, then printing gun parts becomes easy.

$50k is not much to an organized criminal gang. No worries about imports, if this machine will do what you want. Don’t even think about selling the product piecemeal.

Run off 500, then stash them about the country.

Never leave a trail to the manufacture site.

I wonder if the sintering process will eliminate the need for post forming heat treat - or at least part of the heat treat processing.

Not a clue. I hadn’t even considered that. Good question.

I’d have to rummage through my Willys and AMC parts bins and the books to see what I’m in need of. As much as possible I try to recycle current parts. Powder coat and if I have to paint for preservation.

The recent economic upset has put some things on hold.

That being said, my dad has a 65 willys project jeep and his is more needy than mine. Some chassis and other metal parts simply don’t exist any more or the cheap aftermarket stuff is usually junk.

I finally sold my GMC pickup because the forks mechanism that permitted shifting gears just wore out

I’m sceptical however of mechanical properties of the built up product

Keep in mind that a lot of parts get their strength
from the deformation of the grain structure during
the forging process. Not sure how this would work
with these parts.

Instead of powder coating look into cerakote
