INTERNATIONAL WORKSHOP ON STEREOLITHOGRAPHY IN MEDICINE 2nd International Workshop on Rapid Prototyping in Medicine April 7-8, 1994 University of Zurich-Irchel Department of Computer Science MultiMedia Laboratory Winterthurerstrasse 190 8057 Zurich, Switzerland Program Sponsors Ciba-Geigy, Polymers Division Siemens-Albis AG Medizinische Technik Silicon Graphics Computer Systems Philips AG Medical Systems Purpose Computer-controlled Rapid Prototyping is a fast expanding field with a large application potential in medicine and related fields. Typical applications include the making of three-dimensional copies of bones, the producing of in- dividually designed prosthesis models and the replicating of anatomic objects for educational purposes. This 2nd International Workshop is an ideal forum for identifying, promoting, and exchanging ideas on research and development as well as on new applications of Rapid Prototyping in medicine and related fields. A tutorial preceding the workshop is intended for all those wishing to understand how 3D objects are fabricated using the technique of Stereo- lithography, including demonstrations. The workshop is supported by the Swiss Society for Medical Informatics (SSMI) and the Swiss Computer Graphics Association (SCGA). Organizing and Program Committee Prof. Dr. P.
