  1. Thanks Andras! Always appreciate your updates on new Slicer functions.
  2. Eric, we should definitely connect. Anyone else attending?
  3. I will be attending RSNA 2019 in Chicago Illinois this December. Is anybody else in the embodi3D community attending? RSNA is the largest radiology meeting in the world, with over 50k attendees. If you are attending the conference, maybe we can connect to discuss 3D printing? Leave a note here if you will be there. Dr. Mike
  4. Inov3D has listed embodi3D as one of their best website for downloading 3D printable models. Of course, it is the only model sharing website that focuses on medical models in particular. If you don't know about Innov3D, it is a website that focuses on news and information related to 3D printing. They have product reviews, tutorials, and a variety of cool projects to become engaged in. Check it out! And a big shout-out to Inov3D for listing embodi3D as one of their top 3D printable model sites. Dr. Mike
  5. Are you working on a cool 3D printing project? If so, let us know and we might feature you and your work in our newsletter. Send a message to me and let me know about what you are doing.
  6. Check out some of valchanov's work. It might be useful to you.
  7. Version 1.0.0


    This is a fusiform abdominal aortic aneurysm extracted from a medical CT scan. It is a perfect model for medical device testing, hydrodynamic testing, finite element analysis (FEA). The aneurysm is maximally 5.58 cm is diameter. This model represents the blood pool (lumen) of the aneurysm, and includes the following structures: abdominal aorta abdominal aortic aneurysm (AAA) superior mesenteric artery (SMA) right and left renal arteries right and left common iliac arteries right and left internal and external iliac arteries right and left common femoral arteries right and left superficial femoral arteries (proximal) right and left profunda femoris arteries (proximal) Vascular Parameters: Aneurysm dimensions: Length: 6.96 cm Anterior Posterior: 4.9 cm Transverse (left-right): 5.58cm Infrarenal aorta: Transverse: 1.92 cm Anterior Posterior: 1.75 cm Infrarenal landing area (distance from renal arteries to aneurysm): 3.85 cm Right Common Iliac Artery (CIA): 1.35 cm Left Common Iliac Artery (CIA): 1.11 cm 3D printing parameters: Vertices: 113,948 Faces: 227,892 Object is manifold


  8. A member recently asked me this. I am posting my reply in the hopes it will help others. Question: "any advice on choosing a medical CT scan ? best practice for choosing CT for CMF and cardiac cases? that I can give to our radiologist?" Answer: I wrote a blog article that explains all the details on how to select a great scan for 3D printing (link below). For heart cases in particular, try to find a CT scan with ECG gating. This will reduce motion artifact of the heart. Good luck! Dr. Mike
  9. This is an interesting website that has a lot of 3D printing related information, including a very nice comparison tool for 3D printers (link below). It also has reviews, guides, and a "best of" series of articles that will be of interest to anyone engaged in 3D printing. The information is very current. Check it out. https://www.aniwaa.com/comparison/3d-printers/ https://www.aniwaa.com/best-of/3d-printers/
  10. Wow. Great tip. I'm definitely going to try it. Thanks!
  11. Here is an article on the benefits of using 3D printed temporal bones for surgical training https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6703115/
  12. This is outstanding. Thank you very much for sharing. Dr. Mike
  13. I agree. Even with polyjet, there is the issue of wall thickness. The leaflets are very thin and thus hard to print with any printing technology. With great difficulty I designed an 3D printed a customized sheep heart for flow testing of TAVR devices using elastic material.
  14. valchanov, is shrinking a factor with STL prints or just with FDM prints?
  15. Valchanov, I downloaded the file and took a look. I see right ventricular hypertrophy, a large VSD, pulmonary valve atresia/stenosis and an overriding aorta that is also on the right side. I think this is Tetrology of Fallot. It is a cool scan! Dr. Mike
  16. Is it a thin slice series? 791 seems very large, even for thin slices.
  17. 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.
  18. Interesting. Can you give some examples of your work?
  19. 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!
  20. I think this is the biggest thoracic aneurysm I have ever seen. I am glad the patient survived!
