  4. You first need to create a surface object from your volumetric CT scan data. You can do this in Slicer using the "Make Model Effect" tool. A tutorial on how to do this is linked below. Alternatively, you can save your CT scan as an NRRD file (I can see that option in the picture you shared) and automatically process it using the free democratiz3D service. A link to a tutorial on that is also below. Hope this helps.

  6. Does anybody have experience using the Tough resin or Durable resin from Formlabs for medical models. I printed a large spine model in Formlabs white and it seems rather delicate for a large structure -- i.e. I am not sure it can be handled roughly without breaking. Wondering if anyone has experience with tough or durable. https://formlabs.com/materials/engineering/
  7. Here is my review of the Ultimaker 3 Extended 3D printer for Medical 3D printing. I hope you find it useful.
  8. Here is my video review of the Ultimaker 3 Extended for medical 3D printing. It was 4 months in the making. Medical anatomical models can be challenging to 3D print because of complex anatomy and large size. This 3D printer has a couple of features which help overcome these challenges. First, the Ultimaker 3 is a dual extrusion printer which allows for two different materials to be used during a single print. This video shows 3D printing with one water soluble material for support and another material for printing anatomical structures. I show how water soluble PVA provides support during the build and can be easily dissolved in tap water once the build is complete. Second, the Ultimaker has a large build volume compared to most 3D printers in this price range. This allows for anatomical structures to be created in one print rather than having to do several prints and putting the pieces together. While there are several good features of this 3D printer, there is still room for improvement. In this review I successfully 3D print small structures like a vertebra, but struggle with large and more complex structures like human brain and lumbar vertebrae. Watch this video review and follow along as I provide the pros and cons of medical 3D printing with the Ultimaker 3 Extended.
  9. There is an RSNA 3D printing Special Interest Group (SIG) meeting this August 31, 2017 in Washington DC at the FDA. This is an important meeting since we want to make sure that 3D printing remains open to everybody and the FDA doesn't required expensive, proprietary and FDA-approved software for medical 3D printing. If you want to know more about the SIG, here is the page. Non-physicians can join. https://www.rsna.org/3D-Printing-SIG/
  10. This one I used Slicer since I needed to include pancreas, spleen, artery, and bone, as opposed to just bone. It required a lot of manual segmentation.
  11. Glad that worked out. I am also using Slicer (64 bit) and Windows 10 and it works fine.
  12. Amazing how the freeware (3D Slicer) works better than the expensive proprietary software (Mimics), at least for this application.
  13. Here are some pictures and vids. Most notable at this conference was the announcement of the Fuse 1 SLS nylon 3D printed and the Formlabs Cube multiprinter manager. It was a great conference. Enjoy.
