UL Sets 3D Printing Emission Standard

February 14, 2019 / Jeffrey Heimgartner

As the use of additive manufacturing has grown exponentially, so have concerns about emissions from 3D printers. With an increasing number of freestanding 3D printers being used in schools, offices and other enclosed locations, indoor air pollution has become an important concern.
UL, a global safety consulting and certification firm based in Illinois, collaborated with Georgia Institute of Technology on a two-year study focused on these emissions. Based on the results of that research, which were released in November, UL developed the first edition of ANSI/CAN/UL 2904, Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers.
