This is one of my last 3D sculptures totally made in Mudbox 2015.
No basemeshes were imported from other 3D apps like MAX or MAYA.
After the modeling/sculpt process in Mudbox, the fixes for correct 3D printing in all the polished plastics materials was made with Autodesk Meshmixer and using the Shapeways 3D tools in every version uploaded until the model passed all the shapeways tests.Especially the wall thickness.(look the images of the test results)
You can see HD images of the finished HI poly sculpt in the albums in my facebook page:
