the NovaCast takes the form of an open plastic framework as opposed to an enclosed plaster (or fiberglass) casing. This allows it to hold broken bones in place, while still letting the injured appendage "breathe." Additionally, unlike the case with plaster, its plastic construction won't absorb sweat or other fluids. As a result, skin ulcers and infections are less likely to occur, and itches can more easily be scratched.

The technology could ultimately save doctors time, as they would be able to leave the printer to create the cast while they attended to other patients, instead of having to build up a plaster cast themselves.
