Notes on 3D Printing Brains
The basic process is very simple. Scan the subject and create the cortical surface model, then convert to .STL format with mris_convert e.g. for the LH pial surface
mris_convert lh.pial lh.pial.stl
Then send to .STL format to a 3D printer. Billy Gill at UT has a very nice one, prices was $750 for a brain and some brainstems. The BioE core at BCM is buying one. There are some other steps that can printing easier. This website has some suggestions: http://imgur.com/a/3mFsX They recommend downsampling the .STL file with MeshLab
http://meshlab.sourceforge.net/ http://downloads.sourceforge.net/project/meshlab/latest
to <20K face sets.
Filters -> Remeshing, Simplification, and Reconstruction -> Quadratic Edge Collapse Decimation
Then Export Mesh to a new file.
