It's possible, and you have the best tool for it. I have already printed some Poser figures. I use ZBrush to make everything printable. Take your model after you've posed it and bring it into ZBrush. Make it a Dynamesh and correct errors, which may have occured by the dynameshing. The result should be printable with minor corrections.

It should be possible with Blender too, I would try a high-res shrinkwrapped mesh as a starter. But since I do have ZBrush, I did not spend much time with it. 

You need this kind of preparation, the figures usually aren't printable right away.
