I am having an issue with this. I’m using BrainSuite to create a file that I can then print with a 3D printer. I am able to get everything to run beautifully, but I can’t figure out how to get the *pial.cortex.dfs file into a format that the printer software can understand. I see in reply #66 that I should be able to save as .obj, but I can’t figure out how to do that with the menu options. How would I do this? Is there a way that I can save it to stl format?
