This is a skull of a 43yo male that I modeled from TCIA from the QIN-HEADNECK collection, which is available under a Creative Commons Attribution 3.0 Unported License. I modeled it in Mimics and cleaned it up (as best I could) for printing with Meshlab and Meshmixer.
I have printed it on a Robo3D. To prep for printing, I used the Plane Cut tool in Meshmixer to slice posterior to the mandible, making a front and back half. Then I cut the front half down the midsagittal line. I used white MakerBot PLA, 200 micron resolution, outer perimeter print speed of 20 mm/s, 3 perimeter shells, 25% infill.
I have printed the two halves of the front but not the back yet!
