That’s the part that the breathless promoters miss, or don’t want you to hear.
It will be revolutionary for small volume manufacturing, making parts for which the tooling no longer exists (think vintage cars and airplanes), etc.
Yesterday I had lunch with a vintage car friend. He opened his trunk to show me a wheel cover for a 1974 aluminum wheel and he was happy he got it for just $27. He bought 4 of them.
I could have drawn it up in an hour, printed it in another 40 minutes and it would have cost me about 50 cents.
