  • 3D Printable Lace Skull, Half-Size By Dr. Mike

    This half-size skull with web-like texture was created from a real CT scan. The beautiful lace-like structure not only makes the piece aesthetically interesting and strong, but also reduces material cost when 3D printing. The file is in STL format. This is the half-size version. A full-size version is also available here.   If you don't want to bother printing it yourself, you can buy a model at cost from Shapeways.     Please share your 3D printable creations in the File Vault as I have shared mine with you.
    Feel free to print this model for your own personal use but please do not use this file for commercial purposes.
  • 3D Printable Human heart model with stackable slices By Dr. Mike

    -> IMPROVED VERSION OF THIS FILE IS AVAILABLE HERE <--   This 3D printable model of a human heart was generated from a contrast enhanced CT scan. The model comes in 4 slices, and demonstrates the detailed anatomy of the human heart in exquisite detail. Each slice stacks on top of the prior slice to form a complete human heart. Individual slices show the detailed cardiac anatomy of the right and left ventricles, and right and left atria, and outflow tracts. Perfect for educational purposes. Download this model for free and 3D print the model yourself!

    This 3D printable model of a human heart was generated from a contrast enhanced CT scan. This model is an improvement over a prior version (here). Notches have been added to ensure the slices fit together and do not slide against each other. The model demonstrates the detailed anatomy of the human heart in exquisite detail. Each slice stacks on top of the prior slice to form a complete human heart. Individual slices show the detailed cardiac anatomy of the right and left ventricles, and right and left atria, and outflow tracts. Perfect for educational purposes. It has been validated as printable on an Ultimaker 3 Extended printer.       Technical parameters: manifold STL (watertight) vertices: 462576 triangles: 925800 dimensions: 15.1 x 15.2 x 10.5 cm

    This is a well-defined file of the mandible with teeth. The third molars are in deep inclusion and we also have a supernumerary tooth. I was also able to segment and to separate the inferior alveolar nerves in the mandibular canal up to the mental foramen. The mesh is generated with two surface rendering, one for the bone of the mandible and one for the teeth. I think this is a good idea for Anatomical study of the alveolar nerves and the relation of the nerve with the apex of the third molar. For surgical training you can try the cuts of the Bilateral Sagittal Split  Osteotomy, any endodontic treatments or all your imagination let you do. I Hope you Enjoy.    Nicola

      The print looks flawless!  
    • By justmearun · Posted
      Printed to evaluate how complex models were printed in our 3D printer. The print was bad due to a technical issue with the printer, so I am not attaching any images of the print. Will print more of the same model soon. Thank you for the file.

      the most high resolution head scan on the site!
    • By Papy_Yosh · Posted
      Thank you very much for the files, I printed the 4 slices in a total of 64 hours in PETG red. It does take some time, but the result is fantastic. I printed it for my teacher of BIO A&P, she is a crazy about anything related to cardiovascular. I added small 5 x 1 mm earth magnets to hold the slices together. They seem to be te right thickness to compensate for the gap between each slices. Over all, I love that model. I will have to reprint the top slice as my part started to unglue from the bet and has some warp. What you do is awesome and giving it access for free is marvelous.   Again thank  you for your work Eric   I will be starting on the heart attached to the spine very soon

    • Hello   I want to ask if anybody has had the following problem.   To print my models I extract the DICOM files using the ROI segmentation tool of Horos, once I have the STL model I clean it using Meshmixer and finally I prepare it with simplify3D. I have noticed that when I do the PLA models of orthopedics fractures some of them appear (their really are) smaller or bigger than the DIcom files. And when the surgeon uses it before the real surgery some of the materials measured before are useless because there are to big (the use a smaller nail)   I don't know if anybody has had the same problem   Thank you very much for a such a useful website    
    • Hi. I am an amputee needing a left-hand scan for a 3D print project at the University of Tennessee Knoxville. You can verify project with my professor if required. Thank you.
    • Hello Kopachini,   I have some news for you.   While the new GE machines have the facility to export images form DICOM files in STL format (either as a stand alone model or a relief model), they have unbundled the functionality so that the same functionality can be available using their stand alone software called 4D View where older GE models do not have this functionality built in.   This allows you to access a DICOM file and export the image as a STL file.   In theory you can download this software for the GE website, but it is rarely successful. And you need to be a member of the Voulson club.   The only way I have found is to make friends with an owner of a GE system and ask them to request a demo version of the software.   This is what I did.   My (small) company 3D Industries is now working on this aspect as one of areas of activity with a view to commercialization. Let me know what you are doing and we may have a common interest.   Best regards Peter
    • I contacted one private clinic in my city which has 3D US, and they are apparently really good at it. They told me that they are too busy right now so I couldn't obtain new DICOM data, but I will call them again and ask them if I could come. But the doctor who works there told me that they have GE Voluson S10 (newest model) which have build in the possibility to save study as .stl file... same as Philips IntelliSpace portal that was told before. I did a little bit of research and really there it is, but not for S10, yet for E10 model: http://www3.gehealthcare.com/en/products/categories/ultrasound/voluson/voluson_e10#tabs/tab44799EF6884146E1A27A6929FCAB17D5   Keep your fingers crossed so I could have a glance at that machine in a very soon time
    • I'd like to elaborate on this topic a bit, as I recently had another member inquire about this issue. The member was creating a model from a CT scan of the clavicles. As you can see, there are holes in the medial (midline) ends of both clavicles. What is causing this? Is it a problem with democratiz3D? How can it be fixed?


      The issue lies with the patient's anatomy and the quality of the original CT scan. In the human body there are areas where bones are naturally very thin. Sometimes, the bone surface (cortex) can be  paper thin. Also, some patients who have conditions like osteoporosis may have very little calcium in their bones. Issues like this make it very hard for the CT scanner to detect the bone wall, as you can see from the image below which shows the area on the left clavicle that has a hole in the final model (red arrow). The problem isn't with democratiz3D, but with the quality of the CT scan or with the patient having thin bones (how dare they!).  democratiz3D is actually creating the model exactly as it appears on the CT, its just that the CT has holes we don't want!     So, what can be done? If you encounter this problem you have two options. 1) Manually fix the holes in the model with a mesh editor like Meshmixer, or 2) decrease the threshold value in democratiz3D and re-process the scan. Decreasing the threshold tells the system to capture more voxels in your model, potentially capturing more thin or osteoporotic bone. But, be careful. If you reduce the threshold too much (less than 100), you run the risk of starting to capture muscle, organs, and vessels in your bone model. If you are not sure what threshold to use, you can experiment by running your scan through democratiz3D using different thresholds. To save time, I suggest you do this on low or medium quality setting. When you find a threshold that works, you can generate your final model using a higher (and more time consuming) quality setting, like High or Ultra.   If you are familiar with mesh editing software, that is probably the fastest way to correct this problem. Just delete the edge of the hole, fill it in with a new face, and run a quick smooth operation on the area. It's a 1 minute fix if you know the keyboard shortcuts.

      I hope this tip helps.

      Dr. Mike
