<snip> I did a little bit of "old-style" Lost Wax more years ago than I
care to
admit <g>, in a jewelry-making course. Thing is, if the polymer model
is,
as you mentioned, sandable, and if it would melt, it might also be an
interesting way to do that. </snip>
Hi Kris,
Well, as far as I know, the material that this particular system uses is
a powder with a liquid binding agent. I know it can be sanded and
finished, but I don't think it will melt (at least not cleanly), so I
don't think it could be used directly in the "burn out" stage of a lost
wax process. It would only add one more step, though, to sprue the STL
printed item and make a RTV Silicone mold of it. You could then make as
many wax copies of it as you wished, and cast an unlimited number of
metal pieces from it.
Heh, democratization of art, lower prices for living aids - such
impractical and hallucinatory fantasies......
Hallucinate on, Kris! :O)
Best Wishes,
Bill Neumann
