On February 5, Underwriters Laboratory announced a new standard on 3D printing safety. ANSI/CAN/UL 2904, "Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers," is now available. The new standard applies to "freestanding 3D printers that are typically found in schools, offices, libraries, homes, and other non-industrial indoor spaces."
Researchers began studying emissions from 3D printing as the innovative machines moved into workplaces. Numerous studies have reported the potential dangers of breathing ultrafine particles generated by 3D printers. A study by UL Chemical Safety and Georgia Tech identified volatile organic compounds in 3D printer emissions.
In 2017, TSI engineers released their own report, "Assessing 3D Printer Emissions in the Breathing Zone," with recommendations for reducing worker exposure. The study used data gathered by two different TSI instruments, the Engine Exhaust Particle Sizer Spectrometer and a Condensation Particle Counter.
