Sometimes we weld and machine repair dimensions also, not sure why one or the other is chosen.

Inconel having a very high content Nickel, up to 70% and Chromium 30% and Molybdenum up 10%. Makes it very very tough but not hard, good properties under high heat! Racers are using it now. Exhaust is a place.

So how do you replicate to exactness, cast iron, steel, aluminum, magnesium, brass and copper? Even leather, glass, how about the foam in the seats everything that goes into the making.

I'm not a fabricator but many things are still done the ole fashion way. lol

Thing is what is being produced today in secret may not even see the light of day in forty years. I do think in the near future there will be replicators for simple to produce items.
