3D Printers

I remember hearing or reading something about the 3-D
printers last year or so. One used a wax as a
temporary material for complex 3-D shapes. After the
model is finished the wax is removed leaving the complete model.

The UV-laser and tank of resin method is starting to
sound so passé... Though I know that one company who
did use it wanted to use old-fashioned resin and
rubber to make copies as the UV and resin is so expensive. This was at least
five years ago though.

If I ever win the lottery (though I would have to
start doing it!) I had planned to get a CAD-CAM
milling machine; maybe a 3-D printer would be
better...

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.
