The NIOSH Nanotechnology and Advanced Materials Field Studies Team have conducted multiple field studies in a diverse range of small, medium, and large companies using additive manufacturing (3D Printing) technologies.

Join researchers from that same team for our webinar, which will address the current state-of-the-science on potential emissions and exposures from 3D printers. You’ll receive an overview of how to plan and conduct an industrial hygiene assessment in both metal and polymer additive manufacturing environments.

Explore examples of engineering control technologies implemented by companies working with 3D printing technologies, the applicability of different control approaches (including source control technology for capturing emissions at the print head), and examples of cost-effective, easily scalable emission control methods.

Learning Objectives

Upon completion, participants will be able to:

  • Understand key considerations when planning an industrial hygiene exposure assessment for an additive manufacturing environment.
  • Identify emission components and characteristics from 3D printers.
  • Employ engineering control approaches for reducing exposures for additive manufacturing processes.
  • Analyze air sampling results from typical additive manufacturing workplaces.


Lieutenant Commander Kevin L. Dunn, CIH is an environmental health officer in the United States Public Health Service, and an Industrial Hygienist with CDC/NIOSH. He received his M.S. in Environmental Health and Industrial Hygiene from the University of Cincinnati and is a Certified Industrial Hygienist. He has been with NIOSH since 1998 and is currently the Advanced Materials and Emerging Technologies Field Studies Team Leader and the Exposure Assessment Critical Area Coordinator for the NIOSH Nanotechnology Research Center in Cincinnati, Ohio.

Captain Duane Hammond is a mechanical engineer with the Public Health Service. He has a B.S. in Mechanical Engineering, an M.S. in Industrial Engineering, and is a licensed professional engineer. He has been with NIOSH since 2002 and has led a wide range of engineering control research studies to protect workers from occupational exposures to chemical, biological, radiological, and physical hazards. He is currently focusing on a NIOSH Nanotechnology Research Center (NTRC) funded research project to evaluate and develop engineering controls for additive manufacturing/3D printing and has completed 14 field studies in collaboration with the NTRC field team under the NIOSH Nano and Emerging Technologies Program.
