David and the list,
I believe that this whole discussion grew out of Pete Sferro's talk at
the RPA show in Cincy. The focus was on how to expose more students to
RP and design for RP as the equipment moves toward production level
processes. The so called RP in a box in my viewpoint was to be a
teaching tool or home tinker tool that could be built inexpensively and
use some type of common build material as a beginning. Much like many of
the universities and schools compete in design competitions, it was
hoped that it would be possible to create a low cost "reasonably"
accurate machine that could be easily duplicated. My take was it was to
be initially a home grown unit to drive up the knowledge on the
application of RP.
Elaine, can you elaborate more?

I have a hard time getting computers, printers, and copiers less than
$2,000. Of course, it can be done. Computers are now regularly under
$2k, and printers range from the ultimate cheap to $2k. . . But, high
quality copiers. . . hmmm
Why would u want to develop something that would have no margin. And,
if they purchased a $2k system, what would be the ancilary equipment
Computer $1400
Desk $100
Software $2500
Not to talk about software and hardware maintenance.

Doesn't this contest pre-suppose that a $2000 RP machine is a
possibility? Maybe it is possible so then my question becomes if you
know of the technology that would make this happen how come no
commercial company is working on it?

Subject: 3d for 2k event The idea of 3d for 2k has been kicked around
for a number of years... so below are ideas for comments, suggestions,
and flames, plus volunteers......


(3D under $2K)
3 Dimensional Replicator CompetitionVision: To produce functional
designs for low cost machines that can replicate 3 dimensional objects
from computer data models. (CAD, 3D Imaging, and VR file formats)
Mission: To encourage students (and home hobbyists) to build a 3
dimensional replicating system for less than $2K that is capable of
building useful parts.

Goals: Design a 3D replicating system using "off the shelf" or easy to
fabricate parts, that can be built for less than $2000 USD. Thereby
increasing public awareness of prototyping technologies and the use of 3
dimensional replication.
        Must submit an object replicated by the system.
Must describe and demonstrate the operational parameters.
Must describe or demonstrate the use or function of the replicated
        Must identify the costs of build materials and operation.
        Must submit a report with construction diagrams, parts list and
        Must be public domain work.

Time Frame: Work must begin in ? 2002 and final submission of paper and
models must be made by ? , 2003. (ideas of timing are welcome)

Promotion: Entrants must be willing to be interviewed by the media and
promote the competition.

Judging: A committee of business leaders will select finalists based on
quality of replicated objects, ease of use, functionality of objects,
and cost to create the system and the replicated objects.

Finalist Judging: Replicator systems must be operational during event
held for judging.

Publication: All submissions will be posted on a web site with complete
plans and materials lists available. 2004 competition will build on
previous work.
