The West Conn Department of Mathematics and Computer Science, with the Office of Information Technology & Innovation, are manufacturing a component used in the assembly of protective face shields for medical personnel. They programmed a 3-D printer, which was delivered to St. Mary’s Hospital in Waterbury, which made the original inquiry. University officials say another is available for additional hospitals. The effort is part of a statewide project that hopes to build 20,000 face shields in the next several weeks.
