I had the opportunity to print a dinosaur at work ( www.3dphacktory.com ) on the Objet 500, so I remixed IcanCwhatUsay's Tyrannosaurus rex to be larger and use multiple materials. :)Because of the way that the original was created, it was easy to isolate the eyes and teeth in Netfabb Studio and move them into separate files.In Objet Studio, I imported the three files together as an assembly, and chose a different digital material for each one.Download the three STL files: body, eyes, and teethStart a new tray in Objet StudioInsert the three STL files as an assemblyChoose different materials for each part in the assemblyNOTE: I used Shore50 on the body, and it made the legs just a little too rubbery for the dinosaur to stand without leaning back on its tail, so I recommend using something more rigid.
