Keep us informed on your build!
I hope you are successful! These things are amazing!
I can't help you with the motors, but I own a 3D printing business so I can help you with that kind of thing.
There are all kinds of 3D printers popping up!
Here is one that is due out SOON

Here is my latest print done on my Dimension BST 768.
This thing took 24.25 hours to print and used about $100 in material.
Sorry I had to censor this one, but this is by far the most complex model I have printed! This customer does 3D characters and has given me rights to show his model off, so I am not breaking a NDA or agreements.
I have lots of sample parts at photos.printo3d.com
