A study by researchers at the Georgia Institute of Technology has found that particles emitted from consumer-grade 3D printers could negatively impact indoor air quality and potentially harm respiratory health. The researchers collected particles emitted from 3D printers and conducted tests to gauge their impact on respiratory cell cultures, finding that there is a toxic response to the particles from various types of filaments used by these 3D printers. The study also found that ABS particles emitted from the 3D printers had chemical characteristics that were different than the ABS filament and that better ventilation would limit the amount of exposure to the emissions in commercial buildings, but in residential settings with less effective ventilation, the exposure could be much higher.
