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.
