the other way would be to buy a large format printer, something like this: http://www.formbot3d.com/formbot-rap...ing_p0022.html

and print your own.

For cutting models into parts I actually use flashforge's slicer: flashprint. http://www.flashforge.com/flashprint/
And then export the seperate parts as .stl files.
It's the only thing I use flashprint for :-)
