[Neuro] 3D Printing Brains!

Hi Kelly and everybody,

I just LOVE this idea!   Thanks for promoting it and making the wiki  
page Kelly.  What a great way to learn about 3-d printing.  The brain  
scan I have , and I do have one, is on film.  Do you think there is a  
way I could use it by scanning  it or something?

Mold-making is something I am good at.  So, if we get through making a  
3-d printed model, I can take it from there.  I'd be happy to teach  
everybody how to make a food safe silicone mold for chocolate.   
Silicone would be better than latex, because he's talking about  
putting six or eight  coats of latex on something, and each one has to  
set up, so it takes too long.  Silicone on the other hand, is a fast  
one step deal, and you can all try out the vaccuum degasser I happen  
to have (borrowed), which is really fun to use.
