Aortic Bifurcation

thingiverse

This is a 3D print derived from medical imaging of an aortic bifurcation and iliac arteries. The source data set is publicly available in the OsiriX DICOM library http://pubimage.hcuge.ch:8080/ . It is a CT scan from a patient that appears to have had one or more iliac stents placed in their right iliac artery. The workflow used to create this Thing was (almost) completely open source: AMNESIX Data set: http://pubimage.hcuge.ch:8080/DATA/AMNESIX.zip OsiriX used for segmentation and rough STL export: http://www.osirix-viewer.com/ Meshlab used for cleanup: http://www.meshlab.org/ Final cleanup, slicing, and GCode using Netfabb (http://netfabb.com), which is a bit faster than the open source alternatives. Printed with RepG on an Ultimaker. Using the Netfabb "standard" profile (modified to print at 230 degrees) the full print took 4 hours and 19 minutes. More on the story of this model: http://craig.bonsignore.com/2012/01/17/open-source-human-anatomy/ Instructions Print upside-down, as shown on the bed of the Ultimaker. There are some overhangs that causes a bit of drooping in my print, but nothing too terrible. I had quite a bit of stringing, which I cleaned up using a hobby knife in about 15 minutes. This makes a nice model for engineers or designers working on stents or endovascular aneurysm repair devices. A print like this can be used for a mold to create a bench-top deployment or flow model. This one is printed in PLA, but as a mold core, this would be a good candidate for trying water soluble PVA.
