This project started as a collaboration between Professors Hod Lipson and David I. Owen. Owen, the Bernard and Jane Schapiro Professor of Ancient Near Eastern and Judaic Studies, is the curator of Cornell's collection of nearly 10,000 cuneiform tablets from ancient Mesopotamia. Read more about Cornell's tablet collection at Cornell University's Cuneiform Library. Owen and Lipson had the idea of implementing 3D scanning and 3D printing technology to create physical replicas of the tablets that look and feel almost exactly like the originals.
As well as a demonstration video, so far just three models seem to be available for download as VRML or STL, for color and black-and-white 3D printing respectively.
