Several years ago, some researchers whose identity slips my mind came to visit, and did me the honor of using their system to digitize my face. It was an incredibly high-resolution scan, consisting of nearly 20M triangles, but didn't capture my hair or overall head shape very well. Today I was experimenting with Meshmixer and using it to convert this rough (but detailed) mesh into a much smaller, smoother and manifold surface which could be 3D printed. This model is considerably decimated from the original high-resolution mesh. I don't know why anyone but me would want this data, but I thought I might make it available in any case. I believe it to be life sized, which given the huge size of my head, may or may not fit on your printer. Enjoy, and leave me a comment if you use it for anything interesting.
Update: I went back and reviewed my notes and found out that the scan was originally done by some of my colleagues at Disney Zurich, using the system that they described in a SIGGRAPH 2010 paper:
The original scan was around 20M triangles, this mesh (which I have now printed, as can be seen in the photos that I added) was reduced to around 100K triangles using Meshmixer.
