  1. Is it a thin slice series? 791 seems very large, even for thin slices.
  2. Increase the threshold level. It looks like you are getting soft tissue included with your conversion. Make the threshold 300 or so and it should eliminate a lot of the soft tissue.
  3. Interesting. Can you give some examples of your work?
  4. I've found that printing anatomic parts with a single extruder is difficult, primarily due to limitations on supports with complex, organic geometries. Dual extruder with soluble interfaces is what I use if FDM is required. Stereolithography is also an option although it is messier and arguably requires more postprocessing. Anyone have success with a regular single extruder (excluding specialized setups like MMU)? Mike
    We printed this canine pelvis and lower extremities model with patellar subluxation for a customer in detailed white resin. The model came out great!
    We printed this model for a customer in white PLA. The print took quite a long time, but came out great!
  5. I think this is the biggest thoracic aneurysm I have ever seen. I am glad the patient survived!
  6. Valchanov, as always terrific post. Thanks for sharing!
  7. There shouldn't be. Just know that the unit of measurement is in millimeters. If you import the STL file into printer software and specify that the unit of measurement is cm, inches, or feet, your model will be HUGE. Hope this helps. Mike
  8. Flaviu, Can you go into more detail with your Palette 2 experience? The concept looked great in theory when it came out, but at the time I heard it was still problematic. Are you finding success now?
  9. If you are only interested in bone, the lower dose is probably fine. Make sure you get sequences with soft tissue reconstruction algorithm in addition to the standard bone algorithm. Edge enhancement with the bone algorithm causes speckling, which can make bone segmentation more difficult. See my blog article on selecting a good scan for 3D printing below for details. Look at the section on reconstruction kernel.
  10. A member recently messaged me a comment. I am posting the response here to help the general community: "Regarding democratiz3D, I like that it's simple to use. Being able to convert to even higher resolution STL files for free would be nice." My response: Do you know about our Ultra quality settings? If you set democratiz3D to use ultra quality, you will get an output STL with about 3 million polygons. That is super high resolution. Files of that resolution are difficult to even open on regular PCs because of the extreme detail. Ultra quality STLs take about an hour of server time to generate, and thus we cannot give them away for free. They are available with Premium subscriptions. However, you can still get them for free with our Pay or Share program. If you agree to share your STL with the community, we will pick up the tab for the conversion. It is free for you as our gift because you gave something to the community. Hope this helps! Dr. Mike
  11. Your guess is right. We can't associate shared files with photos of a person due to the need to maintain privacy. Good luck with your project and be sure to post the results here. I am sure the community will be interested in your work. Dr. Mike
  12. A member recently asked the following question: "Is there a skull that would work for someone who is interested in facial reconstruction sculpting or forensic sculpting? I searched some of the skulls but found most seem to have hollow spaces. " We have a variety of skulls available for download and 3D print -- several hundred at least. I am sure you can find something representative of what you need. I am not sure what you mean by "hollow spaces." A normal skull has many hollow spaces, including the paranasal sinuses, mastoid air cells, and of course the intracranial portion where the brain sits. Are you seeking something different? Dr. Mike
  13. A user asked us the following: "Is it possible to get kidneys and near by attached vascular and possible tumors cut out of a CT scan? " The answer is yes. This will probably require lots of time manually segmenting the various structures, but it is possible. It is easiest of the CT scan is with IV contrast and in thin slices. Attached is a picture of a custom print job we did for a medical device company. If you need a custom print print please contact us. If you want to learn more about custom models for medical device testing or other purposes, you can find more info here.
