Chris - That's correct. Something that I failed to mention in my earlier
message is that you must sacrifice the part you want to scan. After encasing
the part in a block of plastic, the machine mills it layer by layer, until it's
gone. 3D digitizing systems fall into one of two broad categories: contact
and non-contact systems. This is very much a contact system. <grin>

Craig Crump is the founder and president of CGI and the inventor of the RE-1000
process. Craig is Scott Crump's younger brother. Scott is the founder and
president of Stratasys and the inventor of the Fused Deposition Modeling (FDM)
process. The Crump family has a lot of invention and entrepreneurship in their
blood. Scott and Craig's father, Ralph, has a number of patents which have led
to many highly successful products, some in the medical field.
