“…The acrylonitrile butadiene styrene (ABS) filament released the most amount of VOCs while the polylactic acid and copolyester filaments leached the least amount of VOCs. More modern 3D pen-printers allow 155 to create various 3D printed shapes while handling the device as a pen. However, the lack of a ventilation system leads to 1.4 to 62.6 times higher VOC emission for the 3D pen compared to the 3D printer when sampled by SPME arrow.…”
