Modeling Exposure and Risks in Emissions of 3D Printer Nanoparticles (AIHce EXP 2021 OnDemand)
Course Description:
Recorded at AIHce EXP 2021

Fused Filament Fabrication (FFF) 3D printers are increasingly used in industrial, academic, military, and residential sectors. Characterization of potential environmental releases and workers/consumer exposure requires further investigation. The session will explore: a) a methodology for evaluation of the potential level of emissions from FFF 3D printers; b) health concerns; c) how environmental measurements can be combined with computational fluid dynamics (CFD) modeling; d) the toxic potential of ultrafine particle exposures; and e) a study to determine nanoparticle emission rates and CFD modeling. In the study to determine the nanoparticle emission rate, the FFF printer, using filaments of natural colored ABS, produced a 40 mm cube, over 4 hours. Measurements of the particle concentrations were found to pass the Hanna test for agreement between model and experimental data.

Upon completion of the session, the participant will be able to:
  • Discuss the EHS issues related to 3D printer emissions.
  • Describe the settings for simulation of 3D printer emissions.
  • Compare measurement approaches to nanoparticle evaluations.
  • Interpret exposure results from the position of toxicological knowledge.
