Turkish designer Mert Iseri was still attending college at Northwestern when he came up with SwipeSense, a portable hand-sanitizer that clips onto the belt loops of a medical professional’s scrubs. Mert and his team created numerous prototypes and iterations, which caused unnecessary strain on the team’s limited resources. The MakerBot Replicator 2 Desktop 3D Printer helped alleviate this strain and in fact, paid for itself within a month. Since their prototyping phase, Mert and crew have completed a clinical trial at Northwestern Memorial Hospital in downtown Chicago, resulting in a 64% compliance rate in hand sanitization throughout the hospital. With a MakerBot in the office, Mert and his team are helping medical pros do their job a lot quicker, and a lot cleaner.Want to share your own MakerBot Replicator 2 story for a chance to win $250?
