Ultrafine particles and volatile organic compounds are generated when using 3D printers. Research has shown that vapors of ultrafine particles and volatile organic compounds are in the vicinity of the printer even after the printing has finished. Ultrafine particles (UFPs) can increase the risks of asthma, impacting the lungs and can also be carriers of toxins inside the bloodstream. Volatile organic compounds (VOCs) are classified by the Environmental Protection Agency as toxic pollutants. Please refer to the
Nanotechnology Research Center at the National Institute of Occupational Safety and Health (NIOSH) (pdf) for more detailed information on these hazards.
When purchasing a 3D printer, be sure to choose one with a built-in ventilation system and/or place it in a well ventilated area inside a lab such as under a snorkel to minimize exposure to UFPs and VOCs. It is also important to note that all equipment brought on campus must first be approved by
submitting an equipment installation request through Facilities. EHS will review each request along with Facilities and provide guidance on proper ventilation for your 3D printer(s).
