    Craniofacial Model, Female 57yo

    Skull and face models were generated in Mimics from a CT scan from TCIA (citations: http://doi.org/10.7937/K9/TCIA.2015.K0F5CGLI, https://doi.org/10.7717/peerj.2057, https://link.springer.com/article/10.1007%2Fs10278-013-9622-7) as reference models for visualizing skin-to-bone relationships for forensic craniofacial identification applications. See Figshare for additional project information.
     
    Face model was hollowed in Meshlab and extruded to this individual's minimum facial tissue depth (1.6 mm) with Meshmixer (tutorial). Cuts were made in 3D Slicer using the EasyClip plugin to cut at specific landmark coordinate values: skin was cut through x-coordinate of pronasale and right oculus anterius, z-coordinate of bony glabella; bone was cut through x-coordinates of left and right oculus anterius, z-coordinate of glabella, y-plane was adjusted until posterior to cheilion.
     
    For 3D printing, I rotated the model until the posterior surface was flat on the bed and added a raft to hold the supports (I left the raft on--see pic), but a custom platform could be added instead with Meshmixer or Tinkercad. I usually leave most of the supports attached to hold the skin layer in place, but remove supports from inside the nasal aperture and sometimes remove supports from the lateral side to reveal the infraorbital foramen. I don't have dual extrusion, but you could probably print the skin in one color and bone in another. The above pics show a print at 300 micron resolution.
     
    **Note that this file contains two merged models that can be printed together or separately--to separate, open in Meshlab, right-click the model name in the layer dialog and select "Split into Connected Components" and save each layer as a separate model.

    Pubic Symphyses, Male 59yo

    These are the pubic bones of a 59yo male (ABD_LYMPH_011) from the CT Lymph Nodes Collection of TCIA, which is made available under Creative Commons Attribution 3.0 Unported License.
     
    I modeled these with the Grayscale Model Maker in 3D Slicer (see tutorial pt. 1), hollowed with Meshlab, fixed for printing with Meshmixer.

    "ABD011_PS_M59_1mm.stl" has a wall thickness of 1 mm to minimize material volume for printing with powder-based printers (for example, through Shapeways)--I would recommend white "strong and flexible plastic."
     
    "ABD011_PS_M59_hollow.stl" is hollow with filled holes--this is what I would use for filament printers, but you could use this to print a solid model through Shapeways.
     
    I also cut the bottoms flat on both so they can be oriented upright to print--I would not recommend printing with the symphyseal face up because the layering process will impose ridges.
     
    If you want to split the left and right halves, in Meshlab use the filter "Split in Connected Components"--once split, each "layer" can be exported as separate .stl files. The "Plane Cut" tool in Meshmixer can be used to further cut the models if you want smaller segments.
     
    If you would like to add shading to the 3D models to enhance viewing of the symphyseal face, in Meshlab apply the Filter--> Color Creation and Processing--> Ambient Occlusion per Vertex.

    I haven't printed this model yet, but I will post pics when I do!

    Male, 43yo, Bifid Nasal Spine

    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!
