Bob,
You should also look at the Envisiontec system.

Rapid Prototyping Gets Faster And Cheaper
Since the late 1980s, rapid prototyping (RP) has evolved from a tool for
making factory molds and dies to a low-volume technique for making
finished parts, and even consumer product prototypes. One type of RP
machine turns computer models into functional parts by creating thin
layer upon layer of powdered metal or plastic, fusing each layer into a
solid. This so-called sintering is done by scanning a laser back and
forth within the part's often-intricate outline. But with most such
machines, it takes hours to build a large 3-D shape.

b.jpg> Behrokh Khoshnevis, a professor of industrial and systems
engineering at the University of Southern California, says he has a
better idea. Instead of sintering a layer by scanning it with a laser
beam, his system quickly fuses the whole layer under an oven-like
electric or gas heater. The powder outside the part's outline doesn't
solidify because it gets treated in advance with a special liquid.
Khoshnevis says his patented approach can polish off each layer in less
than 15 seconds. And it doesn't need a laser, which can cost tens of
thousands of dollars. He has licensed the process and hopes to see
products as early as next year.
