I made the most of the skeleton using Zbrush but some such as the vertebrae were made in 3ds Max and then finished in Zbrush.
After I modelled all of the bones in the skeleton I sent it to the 3d printer.
When the print arrived it was almost ready for painting, just a few areas needed some light sanding.
I painted the print using numerous light washes to make it look like bone.
Once everything was painted and finished all that was left was to assemble the print into an articulated skeleton.
