|Herpes Simplex Virus [message #11560] Fri, 09 April 2010 09:04 UTC
Here is my 5cm diameter model of a Herpes Simplex Virus, printed in alumide.|
After struggling for a very long time with the shapeways software for uploading, the arrival of the new `mesh medic` software finally ironed out my problems.
This model is calculated rather than designed... Virus was imaged in the electron microscope, computational image processing was used to extract the 3D structure which was rendered and converted to STL format using a very cool piece of software called UCSF chimera, I had to reduce the polygon count using meshlab before it was suitable for printing.
I previously had this printed as a gift for a retiring professor at 9cm diameter in metal through pro-metal. Unfortunately some of the finer features were broken off during manufacturing (only one or two, it was still very cool). I gather that the model is very brittle before it is infused with bronze.... Some of the metal models in this forum have some very fine features however. I would be interested to know if these models are likely to be problematic if printed in metal by shapeways.
Many thanks to Bathsheba for helping me through this process!
