An exposure assessment of desktop 3D printing by Tracy L. Zontek, Burton R. Ogle, John T. Jankovic, and Scott M. Hollenbeck
A preliminary hazard analysis of 3D printing included process monitoring in two working environments; a small well ventilated materials development laboratory with a Makerbot printer (polylactic acid filament) and a poorly ventilated lab, home-like in terms of room size and ventilation with a Da Vinci XYZ printer (acrylonitrile- butadiene-styrene).
Particle number, size and mass concentration were measured within the printer enclosures, breathing zone, and room simultaneously. Number concentrations were elevated above background typically in the 103 – 105 particles/cm3 range. During printing >99% of the aerosol number concentration was within the ultrafine particulate (UFP) and nanoscale size range. Condensed aerosol emissions from the Da Vinci XYZ printer was examined by Fourier infra-red spectroscopy and suggested isocyanic acid and n-decane as two possible chemical components. Light microscopy and transmission electron microscopy with energy dispersive analysis by X-ray identified individual and aggregated particles highly suggestive of combustion, accompanied by a variety of metallic elements.
Adverse health effects associated with 3D printing related to chemical vapor off-gassing in well ventilated space appears to be low. At this point the significance of ultrafine particle emission is under growing suspicion in its relationship to inflammatory, pulmonary, and cardiovascular effects. Preliminary recommendations for particulate control developed from this analysis are based on good industrial hygiene practice rather than compelling adverse health effects.

Wednesday’s presentations on Chemical, Sample & Asset Management Tools discussed a variety of aspects of how the safety program collects, organizes and uses data and information related to chemicals and their hazards. The morning’s presentations focused on chemical inventories: why institutions need them; some platforms for collecting and reporting the information associated with them; and what they look like “on the ground”.
The afternoon presentations took a more global approach to chemical safety information in the lab, discussing the organizational, environmental and information contexts of this data. The last speaker of the day described an emerging innovative approach to collecting “Lessons Learned” information from laboratory events,

Tuesday’s presentations discussed the Developing, Implementing & Teaching Hazard Assessment Tools from a variety of points of view, including their impact on lab safety culture; their role as an information and educational process in the laboratory; and how institutions can provide oversight of the quality of this work.
The afternoon session was a 3 hour workshop that discussed how the Bowtie Methodology to hazard and incident analysis can be applied in the laboratory sessions through several examples worked through in small groups.
