This video tutorial goes over how to use the free online service at Embodi3D.com and free desktop software 3D Slicer and Meshmixer to create 3D printable medical models from medical scans. Both online service and desktop software techniques are shown. These are compared and contrasted.
Dr. Mike presents two FREE and effective ways to create medical models from CT scans for 3D printing. Viewers are given a double tutorial on creating 3D printable medical models from regular CT scans in this information-packed video. Dr. mike skillfully alternates between the online method using the democratiz3D service found on embodi3D.com and the desktop approach using 3D Slicer and Meshmixer.
The file pack containing the CT scan with contrast of a head and neck area used in Dr. Mike’s demonstration is complimentary to those who complete the registration for a free embodi3D.com membership!
Starting with an NRRD CT scan file, Dr. Mike shows users how to send a CT scan to the embodi3D service for processing. Those unsure of how to convert a CT scan to NRRD format should check out the helpful tutorials on this process by Dr. Mike on embodi3D.com.
While waiting for democratiz3d to finish processing the NRRD file into an STL file prepared for 3D printing, Dr. Mike instructs viewers how to complete the same process using the free desktop services 3D Slicer and Meshmixer.
In 3D Slicer, viewers are guided on how to use the Greyscale Model Maker module to create a mesh surface model of the CT scan of the head and neck area. Users will never be lost as Dr. Mike delivers simple instructions for each technical setting that must be addressed.
After creating a mesh surface model of the CT scan of the head and neck area using 3D Slicer, Dr. Mike begins the process of converting the file to STL format. Before going into the details of this process, an insightful background of how CT scans are stored is provided.
Dr. Mike leads viewers from 3D Slicer to another free program called Meshmixer, which is available on Meshmixer.com. With Meshmixer, viewers are shown how errors can be highlighted with the Inspector tool and corrected using Remesh with a finishing touch by the less-capable Autofix tool.
By the end of the video, both the STL file generated by democratiz3D and the STL file created by 3D Slicer will be revised using Meshmixer. When these models complete the cleaning process in Meshmixer, Dr. Mike reviews the two files, which are ready to be 3D printed with remarkable anatomical detail!
With this model, viewers will be able to 3D print a head and neck area skeletal model that includes several vital blood vessels like the carotid, temporal, and subclavian arteries.
This video provides the audience with the information needed to decide between democratiz3D from embodi3D.com or 3D Slicer for converting a CT scan NRRD file to STL format before using Meshmixer for final revision. Either choice leads to high-quality medical models that are ready for 3D printing!

Dear Embodi3D and Dr. Mike! Thank you very much, thats cool stuff! But, as mentioned by Deepak Maurya and some other users: files genereated by 3D slicer can´t be saved as STL, the only options are to save it as acsv or txt. I am using 3D slicer 4.10.2, maybe the deleted this function to block STL output? If so, why? Do you have an answer?

[@go_wend_gone]

i am working on a project and your video helps me a lot..thank you

[@josephgeorge495]

can you help me regarding a research. my .stl file is just 1kb and cannot be opened

[@waynesimmonsdmd41]

Dr Mike, thanks for this video. Can you use Dicom from a CBCT scan for this protocol,

[@Gumball_W]

Cool video :-) Do you know how to prepare medical model for finite elemente analysis when it comes to face partitioning ? I mean I have to divide it's surface into smaller pieces on which I will apply some physical conditions. In Meshmixer you can use face groups: select surface with brush, then smooth boundary, use Separate and then Combine in Object Browser. But there are only few file formats available and only some of them save information about such a surface division ...

[@deepak8057173838]

hello sir THANKS for explanation, but i didnot get the .stl file after grey scale module. there is only .txt and .acv option are there. i am using slicer4.7 please help me

[@bernatrocarolsescobedo2514]

I got the same problem, any insight on how to solve it? Thanks

[@carloshernandezbernal6378]

@@bernatrocarolsescobedo2514 Did you solve the problem? I'm in the same situation, only have .txt and .acsv files.

[@rfacurojr]

Can u solved?

[@WillyCi]

Thanks for the video, I been doing the same thing, I tried a lot of software, wish I saw this video 6 month ago (or upload 6 month ago), would save a lot of time.

Great video, thanks a million! What is the cause of the hole at the top of the skull. is this a modelling error or an unfortunate patient?

[@r0hail]

Great content.

[@Implantes]

Thank you!!

[@theoriginalsmidge]

This made me geek happy. Thank you!

[@yuridisaroamado9562]

Amazing tutorial! I'm a medicine student and I have been starving to get accurate 3d printable models for long enough, so I decided to change my goal to learning how to model them myself. Despite anatomy apps having incredibly detailed models, finding some printable ready parts seems to be impossible! There seems to be a big difficulty caused by CT scan artifacts in some areas, e.g., I haven't seen a single full skull model that had sphenoid and vomer satisfactorily accurate for educational purposes. Could I possibly be wrong with that impression? Would it be a waste of time to try to accomplish something that seems that rare?

you all prolly dont care but does anybody know of a trick to log back into an Instagram account..? I somehow forgot my password. I appreciate any assistance you can offer me!

[@kieranbraylon4460]

@Kellen Jordy i really appreciate your reply. I found the site through google and im in the hacking process now. I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.

[@kieranbraylon4460]

@Kellen Jordy It worked and I now got access to my account again. I am so happy:D Thanks so much, you really help me out!

@Kieran Braylon happy to help :D
