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.”
