This is a Star Wars or Star Trek science fiction character. The lines on the face are special sensors for determine the proximity to dangerous gases or humans.
Sculpted this in a 3D modelling application (Modo).
No special instructions here. You should be able to print this with out any support; I have tilted the chin up to account for this.
I have included the model in thing format for Makerware users.
The model is large to smooth out faceting on a high resolution printer.
The image is of a large print at highest resolution on Rep 2.
