Well said! I have been going to my daughters grade school for 3 years now
doing a demo on phase change using polyurethanes and rubber molds and of
course masters made from SL and other technologies. Up until last year I
did the demo for one class of about 26 students and the entire 3rd grade
decided they wanted the demo as well. Last year there were over 150 kids
and each one had a million questions. It is VERY refreshing to be involved
in such an event. At previous years demos I made a small PU figure of a
character my daughter came up with called Clarence the Clayosaurus (the
original figure was made of clay). At last years event I passed out a book
where Shelby (my daughter) and Clarence tell how StereoLithography works.
Attached to each book was a stereolithography figure of Clarence. The kids
ate it up! The demo ends with a race between myself and the teachers using
a foaming PU that (at least, last year) was colored to match red, white and
blue. We mixed the to liquids and the winner is determined by the height of
the resulting solid. There are a million ways to reach kids with this stuff
and in my case it was the thinking of a fresh out of college teacher in my
then 3rd graders class.

You make some good points, however, trade shows are NOT the correct forum,
and RP vendors are not the problem.
Trade shows are VERY expensive, to the point of ridiculous.
An average trade show could cost an exhibitor $10-20K. An extended show like

IMTS could eat $100,000 in a heartbeat. The fault is with convention centers

and show operators who gouge exhibitors at every turn. A $5 waste basket
rents for $15 a day. Bring your own, and you may be charged the same rate,
some venues (like Chicago) the union charges at least $100 to carry it in
door. Sneak it in and your crates and equipment get "lost" or have an
"accident". Chairs and tables go for $50-100. Badge readers rent for $250
the paper they use is separate at $20-60 per pad. These pads have either 50
or 100 sheets, depending on venue. Booth electricity costs more per day than

most of us pay per month in our homes.
These cost have to be justified by sales.

All RP technologies have great levels of "cool" and fascinating, and offer
great appeal to students. Groups of students massed in trade show booths
to crowd out industrial customers, and supplies of sales literature and
sample parts can be depleted in minutes. These show materials have costs
associated, and if you run out, potential buyers may go without. All RP
vendors also have to deal with display models that are stolen or broken.
is not limited to students, but then incidents do seem to increase. Those of

us selling RP equipment all understand the value of cultivating students as
future customers and most have educational programs, but if I spend tens of
thousands of dollars on a show and report to management that I have some
great prospect for 5 years from now, they'll suggest I stop by in 5 years
see if my job is available.
Managers and shareholders want to know what's selling THIS MONTH.

Trade shows seem like a carnival, but they are very serious to those who
exhibit in them. Exhibitors work long hours on their feet, are forced to eat

those damn overpriced hot dogs, and deal with lots of unpleasantness from
show operators. All this with intense pressure to "move the iron".

I remember attending trade shows as a student, and yes, it is a bit
frustrating to not get the same attention as a company president, but
spending too much trade show time on students could cost someone their job.

Schools should do more to promote their own technology seminars. They could
invite vendors and local businesses to attend, as well as students. I've
this work in situations where CAD users meetings are held at colleges. Costs

are low, and students can view the equipment while the group is in meetings.

This seems to be a win for all involved.
 I agree that more should be done to bring students up to speed in the
RP technology, but I don't see it happening at the trade show level unless
costs come down significantly.
