Re: 3D printing, powder spreading

I actually thought of that same thing too, but couldnt find anything
that would harden with alcohol. But the patent talks a lot about the
materials zcorp uses, it even has tables with sample mixtures and
results when testing a testpiece, tensile strength and curing
deformation. That could get us started i guess.
