  1. This was eye openning for me, now is so much easier for me to remove suppots... but after this post I will probably have same problems as you (we from Balkans are very superstitious as yo know at least I am)
  2. And where did your colleagues buy PEEK and for what price if you know? The problem is that medical grade PEEK is still a bit pricey, but not as much as titanium, right? I saw one company on the internet from the states called Vision Miner which print PEEK and contact them for more info about complications etc. ... they have been printing some implants for hospital in Columbia and all that they could tell me that there were no complications but gave me contact of that hospital so I can ask those surgeons more details , but as today I still didn't.
  3. In Slicer PE, now Prusa Slicer, under Support materials, there is a parameter called Contact Z distance, you can increase it to 0.2 (detachable) which makes removing supports more easily
  4. 3D modeling and printing from US data is pretty much the same as from CT... using treshold technique and generating mesh. The biggest problem, for now, is how to open DICOM data obtained from US because it differs to one obtained from CT in one of the software for sliceing (3D Slicer). For now, in 3D slicer you can open DICOM data from GE machines and Philips but people are working on enabling importing DICOM data from other manufacturers. Hope this helps a little bit
  5. Dear olatif2 when in blender, choose edge select and then ALT + LMB/RMB (depending your preferences) and it should select whole edge (tabula externa) than try SHIFT+ALT+LMB/RMB and select tabula externa and than when both edges are selected pres F and sgould get a facet (closed gap). Or faster way would be to add a new object (cube), size it up, put it below both edges and boolean operation difference and should get closed edges of the skull but slightly lower model than it would be at first.
  6. Dear @madjid_hatefi in the link below you can find some promising steps for making a 3D model with Madison US (it is the same as the mentioned above but with new progress). https://discourse.slicer.org/t/could-not-load-ultrasound-from-mvl-medison-file-format/3928/7
  7. ooh, now I see... totally misunderstand question... I didn't realise that he is talking about conventional angiography, sorry
  8. you have several tutorial videos on this web page how to segment a model. but instead of bones which are in the video, you choose contrast blood to segment. https://www.embodi3d.com/tutorials.html/
  9. And are people from other countries allowed to participate or only for folks from the USA?
  10. If I hear or find out something new I will let you know. Sometimes take a glance at 3D Slicer forum (or link above) and maybe sooner or later something will come up ;). P.S. I know your struggle if something is not free :/
  11. I found in the 3D Slicer forum this topic that may help you. There is software called TomoVision that could help you, but you must buy it. https://discourse.slicer.org/t/how-to-import-a-mvl-file-format-3d-ultrasound-image/3294
  12. I am sorry, I didn't have opportunity to work with that model so can't tell you is it possible to make 3D model. Do you have DICOM data maybe to share?
  13. Wow, nice. Thank you for your true review of MMU2. Unfortunately, new orders for MMU begin in February 2019 and can't wait for it to begin Those prints look great. Are there any difficulties when printing ABS/PLA and PVA as support together in one print? PS. @Dr. Mike is this Palette Mosaic same thing you told me about in RSNA meeting?
  14. @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
