Re: 3D Printers

Late last year, I heard about a "3d printer" that used thin sheets of 
paper.	The paper had some kind of contact glue on the bottom side.  A 
continuous roll of these sheets would scroll by, above the model.  And a

laser would cut the outline from the paper.  Models would be built up 
like this.  The result looked like it had been carved from phone book
paper.

I don't have any ideas of how much this process costs, or weather a mold

could be made from it...Certainly sounds faster though.
