Zach, and others.
I would highly recommend seeing what is already available.  Also. As far as molecules for bio chem, what is it that you feel you need to print in 3D.  While 3D models are always preferrable, they are often not as useful as one might think or if they are someone probably already has one that you could use.  
Just a thought...

Ours is 5 by 5 by 5 making it one of the smallest but 10 x 10 x10 would be considered very large for this class of printer. Since the cost of the printer is tied in large part to the print size larger printer are not that common in educational institutions.
