    Thanks for your inquiry. The Conveyed-Adherent process has been renamed
"Offset Fabbing." The article that the abstract you quoted is from is at There are no service bureaus for
this technology yet because I have not yet succeeded in taking the
technology to market. I have been attempting to commercialize it in the form
of an office machine to be called the "Genie Studio Fabber." Besides the
office market, there are also interesting industrial applications, such as
very-large-capacity fabbing, metals, and automated lay-up of composite
prepregs. A working prototype was built and construction of a production
prototype was begun, but mostly I have learned so far how hard it is to
bring a new manufactured product to market.

    If you need some RP done, Southern California has some veteran industry
service bureaus, like Scicon, Solid Concepts, 3-D CAM, Rapid Product
Solutions, and Soligen. Also, the closest technology to Offset Fabbing is
LOM, and you can get that from Cubic Technologies in Torrance. For contact
information on these and a dozen more shops in the area, check out Ed
Grenda's definitive directory at

    Good luck, welcome to the industry, and Happy New Year!
