    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

    Lumbar Spine - Bone model STL file from converted CT scan

    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.
      Each lumbar vertebra is formed of: A body which is kidney shaped and is convex anteriorly while flattened posteriorly, pedicles and lamina, transverse processes, articular processes and a spinous process.   This models shows lumbar spondylo-degenerative changes in the form of marginal osteophytic lipping.   This 3D model was created from the file STS_037   The original CT examination can be reviewed at:

    Lumbar spine wedge compression fracture

    This anterior wedge compression fracture of a lumbar spine vertebral body was generated from real CT scan data and is thus anatomically accurate as it comes from a real person. It shows the loss of height in the anterior vertebral body when compared to the posterior part of the body. This type of fracture is common with forward flexion, such as a from a fall or motor vehicle accident.

    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.

    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!

    Pubic Symphyses, Male 60yo

    These are the pubic bones of a 60yo male (ABD_LYMPH_004) 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.

    "ABD004_PS_M60_LR_1mm_cut.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."
     
    "ABD_004_PS_M60_flat2.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.
     
    I've included a screenshot showing how to split the left and right halves in Meshlab using 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.

    • Once I upload my CT scan to have an STL file and get the file I download it to my documents folder but can't find it.  I got an error message that said it couldn't be opened because it was .stl format.  Is it hidden somewhere? Dan    
    • You can check this tutorial https://www.embodi3d.com/democratiz3d-user-manual/#Quality
    • I wanted to know that, is there any size difference between the .stl file generated form CT scan and the actual size of the skull of the patient. at the conversion, is there any dimensional change could be happen in the software. 
    • It's amazing to see that i had the same problem and question. I usually avoid the Contact Z distance. Anyways, I got information from several places regarding any problem in 3d printing.
    • First of all, a lot of people in the "professional world" are using Ultimakers. And the Palette 2 is still not working with 2.85 filaments (and probably never will?)   The last few months I came across a new scenario for multi material printing. It is mixing PLA with PETG for supports. PLA and PETG don't bond to each other. So you can print your part with PLA and supports with PETG (or vice versa) and set the contact z distance to 0(!). It works very well. Supports are coming off easy and the interface layers look as good as if you were using soluble supports. Since you have to keep soluble filament in dry conditions it is much easier (and cheaper) to use PETG instead.    Setting up the Palette is very easy. Mosaic has some videos one can watch like this one https://www.youtube.com/watch?v=uqbMw_M07GM (and the two follow up ones).   As for my experience. The combination Prusa MK3 + Palette 2 is probably one of the most used one in the community and works very reliable (of course there is no 100% guarantee but lets say 98,5% of the time 😉) . And I always use and recommend Prusas.    Also I would recommend using this post processing tool for PrusaSlicer 2.0: https://github.com/tomvandeneede/p2pp for an Prusa+Palette combination.    I would also still strongly recommend the already mentioned DIY canvas hub guide. There is already an Octoprint beta version out for the new Raspberry 4 so chances are the guide might work with the new Raspberry 4. But I haven't tested it.
