3D printed model of a human inner ear (cochlea, vestibule and semicircular canals) derived from MRI data of a human cadaver. Printed about 12X actual size.


Derived from MRI vrml file from McGill University (http://audilab.bmed.mcgill.ca/~daren/3Dear/inn1.html), I converted the vrml to stl, carried out 25% mesh reduction using Rhino3D, played with the orientation (there is only one orientation that prints well even with support). Printed it on a Replicator with 5 shells and 5% infill in ABS on a raft with exterior support.

I tried to make a model from one of our patient's data today but our resolution is obviously not as good as Yours.
I used data from a T2 spc3d sequence with a resolution of 0.6 mm.
What are You using? And -out of sheer curiosity- why "of cadaver"?
Our patient was still alive and kicking, so to speak ;)


Printed it today with PLA, printed fine, 3hours 20 minutes. Friend works as an audiologist, she will use it to discuss balance problems with patients. Thanks a lot.
