Rapid prototyping has become a fairly common technology in a process that allows specialists in anthropology, forensics and medicine to build detailed likenesses of individuals. While RP is not the only way the work can be accomplished, it greatly facilitates the procedure by allowing direct fabrication from data generated by CT scanners and other medical equipment, and by preserving the original specimens. Some of the work is quite striking in its ability to speak across the ages. One such case is that of the Iceman, recovered a decade ago in the Alps. Another is the restoration of this mummy from the Toledo Museum of Art which was done last year by scientists from the Spectra Group Limited of Maumee, Ohio. Using digital data from a CT scan of the mummy done by the Toledo Hospital, a stereolithography model of the skull was produced by SGL. Forensic specialists then reconstructed the face and head based on the model and historical information. This gentleman is believed to have been a priest that lived around 800 BC and his mummy has been in the museum since 1905.       The CT scan of the mummy (A), 3-dimensional data developed from the scan (B), and stereolithography skull model (C).
