UL publishes 3D printing standard for testing and assessing particle and chemical emissions

UL Chemical Safety has announced the publication of a 3D printing standard which aims to mitigate the risk of indoor air pollution.

ANSI/CAN/UL 2904 ‘Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers’ is now available for use. The standard applies to freestanding 3D printers, typically found in schools, offices, libraries, homes, and other ‘non-industrial’ indoor spaces.
