[chbot] 3D printer demo

[Mark Atherton]

Hey Robotics guys...

A mate of mine is organizing a talk for the local radio club (Branch 
56, Riccarton) and is interested to know if someone with a 3D printer 
(preferably home-made, maybe RepRap) would be willing to bring along 
their kit and do a demo one evening. The club meets on the Fourth 
Tuesday of the month. Audience size is in the region of 20-30 people.

As a possible talk outline:
- a couple of words about history of this new, home-made technology
- words about the associated community
- how much did it cost to build, where did you get the parts from
- how much does it cost to run
- what are the limits on what you can make
- show off some samples
- do a short, live demo

anyway, that is what I might cover...

Please drop me an email if this appeals, I can get more details.

Many thanks,

Mark
