    3D Printer Ready Human Hyoid Bone

    Methods
    3D Medical imaging data was obtained in the .stl format. The hyoid bone was localized from the .stl --sectioned off in the software -- and that part of the anatomy was revised using 3D modeling techniques to be highly adaptable to 3D printing platforms for potential regenerative medicine applications.
    Author and Licensing
    This hyoid bone re-topology was performed by Chris Leggett. It is free to use for research purposes, with modifications as needed, and any future clinical purposes with standard citation practices for using this material and under the creative commons attribution license.

    Cervical spine .stl file from CT scan

    This is a .stl file produced from a CT scan of myself.
    I used 'InVesalius 3.0 free' to convert the 2D dicom images into the .stl file.
    I use either 3D Tool or Materialise's MiniMagics (free versions) to view and manipulate the 3D image.
    I have been told I had a severe hyperflexion injury to my c spine during an assault in 1988 and sustained a number of fractures and subluxations which were not diagnosed by a hospital as they discharged me from the ER in error before I had been examined by a Dr. It wasn't until I had a CT scan in 2011 and produced 3D images from it that I discovered various bony abnormalities that were subsequently identified as fractures & subluxations by experts. I understand the right transverse process of T1, tip of C6 spinous process and the left greater cornu of the hyoid bone are the most obvious old fractures that can be seen.

    Pelvic Bones 3D Printable STL File Converted From CT Scan

    The bony pelvis is formed by 4 bones; a pair of hip bones, the sacrum and the coccyx. The bony pelvis supports the pelvic viscera and works to transmit force from the axial skeleton to the lower limbs.   The two hip bones are related anteriorly at the symphysis pubis and posteriorly to the sacroiliac joint bilaterally. This particular 3D model shows some irregular material floating within the pelvic cavity which represents a contrast media in the colon, that contrast media is given for patients prior to CT scans to distinguish intestinal loops.   This 3D model was created from the file STS_044. This file was created from this CT scan.

    Pubic Symphyses: Male, 18yo

    These are the pubic bones of an 18yo male (ABD_LYMPH_010) 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.
     

    "ABD010_PS_M18_1mm.stl" has a wall thickness of 1mm to minimize material volume for printing through Shapeways--I would recommend white "strong and flexible plastic."
     
    "ABD010_PS_M18_closed.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 haven't printed this model yet, but I will post pics when I do!

    Vertebral column (Dorsal, Lumbar & Sacral spine) - STL file from converted CT scan

    The dorsal (thoracic) spine forms the middle portion of the vertebral column extending below the seventh cervical vertebra to above the first lumbar vertebra. The dorsal spine is formed by twelve vertebral bodies.
    The vertebrae forming the dorsal spine are unique in shape as they are the only vertebral bodies articulating with ribs.
     
    The lumbar spine represents the mid-lower segment of the vertebral column and is composed of five adjacent vertebrae. They are convex anteriorly to form a lumbar lordosis. The lumbar spine facet joints allows limited movements and rotation.
     
    The sacrum is the lower most segment of the vertebral column and also forms the posterior wall of the bony pelvis. The sacrum is formed by five fused sacral vertebrae.
     
    This model shows the origin of ribs, few of the cervical spines and the sacroiliac joint. The minimal tilt seen is likely positional rather that pathological.
     
    This 3D model was created from the file STS_036. The source CT scan used to create this model can be found here.

    Pubic Symphyses, Female 41yo

    These are the pubic bones of a 41yo female (ABD_LYMPH_005) 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.

    "ABD005_PS_F41_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."
     
    "ABD005_PS_F41_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.

      Nice file. What is the scaling factor to create a accurately sized adult heart?
    • By Dawnmferguson · Posted
      Excellent model! I ended up printing it on a less than awesome Dremel 3D printer, then made a silicone mold off of it so I could make wax crayons. I split the mesh in Fusion 360 so I could make a 2 part mold, but ended up only pouring into each side. Still great!!
    • By jvonachen · Posted
      It looks great in the pictures but I did not bother printing it because it would have generated a ton of support material which I try to minimize.  I was looking more for just a single seamless skull with minimal support.  Perhaps one in two parts and hollow.  I'll keep looking.
    • By shadowwynd · Posted
      Good model; prints in one piece (no moving joints or removable parts).  Needed it for an art project.
    • By yf2233 · Posted
      Really nice heart model, you can see the veins. Part of the model broke when I was removing support material. This was printed along with other 3D anatomy files form this site on our Stratasys printer in the lab  Thank you!!

    • Hi all,

      My first attempt at creating a bone print of dog radius ulna using the fantastic Embodi3D procedure .  

      I see there is too much filling in of space between between and around antebrachial bones  -  this is not evident on the original CT.  Can I tweak settings to better isolate radius and ulna ?  I see beautifully isolated examples on this site and feel I am missing a trick here!  

      One point - our CT is cone beam - does that make any difference to stl creation ?

      Any advice much appreciated.

      Martin
    • Medical 3D printing isn't at a point where a user can buy a printer, plug it in and do a few prints a year. There is a big learning curve a user must go through in order for prints to turn out correctly. This is especially true for medical trial exhibits where certain anatomy or conditions need to be highlighted from a CT scan. This requires 3D printing expertise and medical training.   Furthermore, you will need space and all the related tools that go with 3D printing. Some printer manufacturers show their printers sitting on an office desk. This really isn't practical because of the noise, heat and messy post print processing.   We offer a 3D printing service specifically for medical trial exhibits: https://www.embodi3d.com/3d-printing-anatomy-models-for-medical-malpractice-trial-exhibits/    
    • Here is a small sample, you can compare opening in slicer vs opening in mimics. I feel like it has something to do with it being 16 bit but mimics should be able to detect that. Any ideas? WitmerLab_Crocodylus-porosus-OUVC10899_prescan0617.dcm
    • Hey, I have looked through the forums a bit, and there are some instructions and recommendations about specific printers, but I was hoping one (or more) of you guys could comment on what printer/model might be best for me.     I work in a law firm, and recently we've been toying with the idea of printing models of some of our client's scans.   Not an everyday thing, and price and relative ease of use would be important.    So: Relatively easy printer to use Decently supported Limited use (not everyday printing, probably 4-6 big prints a year only) Price may be important   Any ideas on printers and models?
