This is a 3D-printed Tyrannosaurus Rex skull. The size is approximately 17 x 10 x 14 cm. It was made with a stereolithography 3D printer, resulting in a beautiful and detailed finish. As it is 3D-printed, there are layer lines and support marks. The skeletal model uses a commercially available 3D scan data from the Smithsonian Museum. https://3d.si.edu/object/3d/tyrannosaurus-and-triceratops%3Ad8c62d28-4ebc-11ea-b77f-2e728ce88125
