  1. @valchanov I am from Croatia, so Prusa is my choice . Yes, taxes can be really high, especially for us in this part of the Europe, right? Last year I saw a really excellent DLP printer (Gizmo) from Australia, but when you sum tax to the price... unfortunately was too high for me
  2. Was it hard to build one from a kit?? Kit is 300€ cheaper than preassembled one.

    Flexible and Elastic Material

    I am planning to buy this printer and later on multi material update, so please upload some pictures

    3D Printing My Skull

    what is the model of the 3D US? I was able to do model from GE and probably could do it from Siemens Acuson x3000 (I didn't have proper volume, it was my kidney not fetal face ). I tried from Philips US but also didn't acquired right volume (cardiologist didn't know how to do it) and I didn't have much time to read the manual of the machine.

    3D Printing My Skull

    Not much... if you want to make a model from 3D US it depends on who's US machine you are using (there was a problem with GE machines and their Kretz file but thanks to @Andras Lasso he managed to overcome this problem in 3D Slicer). Go to 3D Slicer forum and you will learn how to open and make 3D model from .vol type of files.

    3D Printing My Skull

    Probably, your DICOM data is from CT or MR study of your brain, right? Anyhow, in that case only neurocranium (upper part of the skull) containing the brain was part of the interest in the performed study, so viscerocranium (face) wasn't in the region of the interest (ROI), therefore there is no part of the skull below the middle of the orbit in your DICOM data. Unless you have had trauma and whole head was scanned, than I am not sure what is the problem (maybe damaged DICOM files...)

    Best CAD software for anatomical modeling

    Dear Aris, as you found out Geomagic Freeform and Materialise 3-Matic for 3D modeling are very expensive (annual license cost between 5000 -11000 € depending what features are included, what field you want to use them for, etc.). But there are also open-source softwares like Blender, Meshmixer, Meshlab (more for engineers), MeVisLab... Unfortunately, Blender and Meshmixer, alone, don't have all these features as Freeform, but if you combine two of them you can make pretty decent models with great accuracy. You should familiarise with that softwares, and there are lots of tutorials available on youtube, and internet pages like https://www.blender.org/support/tutorials/ , and https://blenderartists.org/forum/ ... Hope this helps a bit
  8. Here are two volumes obtained by GE Voluson E10 and exported as .stl file. I think that a lot depends on fetal head position and gestation age if you want to have nice fetal face model. Personally, I wasn't present when study was made.

    Vessel reconstructions

    Dear Jee Lee, if CTs are done in arterial phase you will hardly be able to show venous system by automatic segmentation, maybe if a really late phase more porto-venous phase is done you will have some more success. I would suggest that if you have arterial phase only, try automatic segmentation for arteries and try manual segmentation for veins. Or obtain porto-venous phase CT study.

    Femur DICOM

    Dear @kreeser1 under Downloads you can find a lots of DICOM data and .stl files for download. Here is something I found, maybe it helps https://www.embodi3d.com/files/category/44-extremity-lower-leg-cts/
  11. 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
  12. Hi everyone. So, I didn't want to write anything until I make a model from US, but unfortunately, I am still in process of making one. I managed to save study in DICOM data, BUT :(, I have only one file (not several as in CT studies). When I try to upload that data in 3D Slicer it says that that file doesn't have volume (geometry information). I contacted 3D Slicer help and they couldn't help me (they advised me to try to check data by myself)... since I am not so familiar with software and data, I have contacted official service for GE in my country and they said that, probably, the problem is in 3D Slicer, that it can't read dcm data from GE machine. Since I don't have access to 3D US machine (it is not in my department and I depend on one colleague during clinical program/exams and his shift one day a week), I am now stuck. As soon I make some progress I will let you know, or if anyone has any suggestions, please help me or let me know :).

    FDA Legality Question

    FDA approved software (MIMICS and 3-Matic from Materialise) must be used only for implants design (as said in 3D SIG and FDA meeting last year). Regarding making patient specific models for surgery planning etc. you can use other software (open source). @Dr. Mike correct me if I am wrong, since you are from the States

    How to section a skull in half

    I agree with dr. Mike. Try also in Meshmixer plane cut option. Just simply choose which side you want to cut and cut it (you will find some videos on youtube how to use plane cut in Meshmixer).
  15. Hi everybody, I want to make 3D model from 3D US, too :). I was at our gynecology department and they have GE Voluson S8 (I think). I tried to copy several 3D scans and now I see that I got only single file, .4dv extension that I couldn't open with 3D Slicer. I downloaded instruction manual for that US and will read it, until then please tell me what I did wrong and am I on a good way :)?
