Maybe I'm wrong, but I think that if I intend to sell the products of
the machine, which I certainly would, that would be a commercial

Well, that's just my point: there _isn't_ a commercial machine that
does the application I want. Solidscape restricts its use of its idea
to the manufacture of tiny models, and I'd like to make bigger ones.
It would no doubt be expensive to make such a thing (the question
wouldn't have entered my head, did I not have offers of considerable
assistance with the technology), but it's not as though what I'm doing
now is either cheap or satisfactory.
