For my final college project I made a 3d cat skeleton, which I animated walking and also 3d printed.

Cat Skeleton from Ashleigh Chaney on Vimeo.

Step 1:

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.

Step 2:

After I modelled all of the bones in the skeleton I sent it to the 3d printer.

Step 3:

When the print arrived it was almost ready for painting, just a few areas needed some light sanding.

Step 4:

I painted the print using numerous light washes to make it look like bone.

Step 5:

Once everything was painted and finished all that was left was to assemble the print into an articulated skeleton.

Step 6:

The finished piece
