I know this is an old thread, but I too discovered this model and decide to print it. I downloaded the Z brush models posted by Joe, and had a friend convert them for me to OBJ.
The resulting OBJ files are simply huge. I couldn’t work with these models without the apps crashing every 5 minutes, even on a pretty decent PC system with 24GB of RAM and Xeon CPU. So I loaded them into MeshLabs and decimated the mesh to 1/2 of it’s original number of faces.
Even then, manipulating the model and working on them proved to be slow, however using MeshMixer I was able to separate it into groups of parts which allowed me to work without crashing or running out of memory every 15-20 minutes.
Using some of the MeshMixer tools I was able to thicken parts that were too thin, fill in areas that were hollow or interconnect parts that were floating in mid air (This model contains thousands if not tenths of thousands of small part and bits).
I now have more than 60 hours of work in the upper torso alone, as well as a failed print (it failed because the right arm was not connected to the socket so it ended up as blob at the bottom of the tank).
My print is not as large as the one Mattia has done (it’s 1.4 times the original mesh size, or about 10-11" tall without the rock, but I kept more of the very small details, like wires and such.
So far I printed the upper torso, and I still have the lower part (legs, rock and debris) to go, but once I get it printed I’ll start a fresh post with pictures.
