Molding A VERY Complex Object. Is It Even Possible? Part 1.

I love all thing dinosaur!
So the opportunity to mold and cast a Daspletosaurus skull model made from a scan of an actual fossil was thrilling to me. Daspletosaurus is in the Tyrannosauridae family and is a close relative of Tyrannosaurus Rex. The skull is a very complex object and very challenging to mold and cast. It was necessary to break the skull into sections to simplify the pieces. I molded each section in silicone rubber and made the castings from urethane resin.

Thanks to Jesse for sending in this project.

Here is a list of suppliers for the rubber, resins and waxes I use in my videos:
