[hackerspaces] Giving a talk on 3D printing and need some help

[Phil Broussard]

Long story short, I have to give a last minute talk on 3D printers 
tonight. They have it listed as a 2 hour presentation so I need some 
help. To make matters worse the only printer we have working decided to 
have a stepper motor die. So now I have 10 hours to make this work.

Any good suggestions on topics I should cover? I'm going to try and 
cover open source hardware, history, how printers work, current uses and 
anything else you guys can help me think of. I'm also going to try and 
put together a one page handout that will help get people more 
information on 3d printers.

So anything you all can do to help me out would be greatly appreciated.

Thanks!

Phil
