Wow, Steve, been a while since I've seen anything with your name on it! :)
And if you're referring to yourself there in that last sentence, I think you can
easily afford to call yourself something a lot better than an 'amateur.' ;)
As for the printer...I like that plaster idea. It's fairly simple, it requires
nothing super-unusual like high-Class lasers, and perhaps the water part could
even be done with pneumatics or some such thing. Fine motor control with very
small backlash is possible, so I don't see why not.
It would require writing some custom software, but you could probably do that,
right?
The problem is...all that plaster could get expensive.
Really neat idea though!
