Shapeways is trialing a new material which it calls Elasto Plastic. I wonder if this would be any good for making molds? It will only be available until July 20, so we will have to be quick!

<edit> Reading the details, it looks as though this material is only applicable to decorative items </edit>

That's the case for all materials on Shapeways. Even for WSF!

That said, there's no way this could be suitable for making molds. And even then, didn't we discontinue making molds long ago since printing is more time/cost efficient?

Ouch.

I at least want to make a stretchy Rubik's cube out of this.
