One of the best free workflow tutorials I have seen for a fully realized model,printing from a 3D package.
If you are using other 3D software and want to know if it can do this too, the answer is no. ZBrush rules.
Seriously though,not many packages can do this to the degree Zbrush does;however,you can output all kinds of models and parts from many different 3d programs. This is just a great free tutorial for one of the best in my opinion.
Should help answer some questions I hope. http://www.pixologic.com/zclassroom/homeroom/tutorial.php?lesson=jeff
