I don't want everything made out of abs plastic. Has anyone come up with designs that can incorporate other materials?
I'm not sure I understand what you're asking for.. Shapeways has materials from Gypsum, to Nylon, even Steel and Glass.
That's an awesome idea. Print a candle design? I think the challenge in this for printing would be getting the wick in there.
You could just leave a hole and pass the wick through it after printing. That's the way those cheap tealights are done. Greetings Dragoman
