UL Releases Summit Proceedings for Safety Science of 3D Printing

Estimated reading time: 1 minute

UL, a global safety science organization, releases the proceedings from "Safety Science of 3D Printing," a leadership summit with participation from more than 45 stakeholders—including printer manufacturers, material suppliers, public health professionals, academic researchers, school users, and government organizations.

Underwriters Laboratories Inc., a not-for-profit organization that is part of the UL family of companies, is investing in independent human health research to provide consumers, manufacturers and policymakers with a greater scientific understanding for identifying and reducing potential health hazards. Research results were released following a two-year study of emissions from desktop 3D printers conducted by the Georgia Institute of Technology, Emory University Rollins School of Public Health, and UL's Chemical Research Initiative.

Results indicated that printers can be a source of ultrafine particles and volatile organic chemicals to the indoor air while operating. An environmental chamber methodology was developed for studying emissions and monitoring their behavior over time, and comparative particle toxicity studies were presented. Supporting research was presented by other key public health and academic organizations.

Dialogue among the participants focused on measurement methodologies; exposure models; continuing research needs; toxicity measurements of particle emissions; and communication to the public and users of 3D printers for minimizing emission exposure and public health impacts. According to Dr. Marilyn Black, Senior Technical Advisor to UL, "Based on research results and safety concern over these emissions, stakeholders agreed to move forward with UL taking a lead role to develop an ANSI standard for measuring and assessing printer emissions for safe use in indoor spaces."
