Cranium and mandible of the Visible Human Female segmented by me from a computed tomography (CT) scan. I downloaded the “Aligned CT Dicom” provided here under CCBY 4.0 license and segmented the cranium and mandible separately in 3D Slicer. I made the models solid to simplify 3D printing, so there are no internal surfaces.

Cranium (14h7m):

• 0.20 mm layers, 3 walls, 8% grid infill
• tree supports at 30 degrees
  • Top Z distance = 0.20
  • Top Interface spacing = 0
  • Top interface layers =2
  • Branch diameter = 2

Mandible (2h53m) (will fit on a small printer like the mini):

• 0.16 mm layers, 3 walls, 8% gyroid infill
• tree supports at 30 degrees
  • Top Z distance = 0.16
  • Top interface spacing = 0
  • Top interface layers = 2
  • Branch diameter = 2

My models in the pics are printed with Sunlu matte PLA in bone white--matte PLA makes support removal much easier. I ended up with some ugly short seams on the occipital surrounding the overhang area--I tried different settings and rotating the cranium but the changes didn't affect those little short seams. Printing at 0.16 might reduce them a bit. 

I added a little cylinder off to the side so I could raise the parts off the bed to prevent flattening of the bottom surfaces. Remove it if you want.

This CT scan is not high resolution, but I have tried to capture as much detail as I could see. Additionally, this individual was older so she has tooth loss and alveolar resorption as well as cranial suture obliteration. 

This would make a great addition to a a skeletal collection for osteology, forensic anthropology, bioarchaeology, or biomedical courses especially to demonstrate age-related changes.
