I tried to upload the complete model here but it fails, so I added it to http://www.thingiverse.com/thing:1444970 . You can download the file Einstein_bust_300.stl , this is the complete model. Enjoy printing the model!
I had to cut the model into 11 pieces so it fitted my 3dprinterlab.org standard Prusa i3 (200 X 200 Y 220 Z build space), printed with a 0.4 mm nozzle.
After printing the parts I filled them with plaster and glued them together with epoxy. Then I sanded down the joint and gave it a coat of Zinc primer and sanded down the model very lightly to preserve the 3d printer artifacts. Finally I gave the model 3 coats of golden spray paint.
