摘要

This safety issue is difficult to diagnose at the present time due to the limited research currently available. However, based on the most recent studies, the authors do not believe that schools and teachers should be overly concerned about operating a 3D printer in their laboratory if it is using PLA material and is in a facility with a room-change ventilation rate of at least 3 volumes of the room per hour. Newer, enclosed style 3D printers often feature a built in filter for UFPs; however, it is better professional practice that all 3D printers only be minimally operated in adequately ventilated rooms. At the present time, the more prudent approach is to operate 3D printers in fume hoods or spray booths. Teachers, administrators/supervisors, and school systems in general are encouraged to keep an eye on emerging studies that will continue to reveal more about the potential health risks associated with this technology.
