Neuroendocrine effects of inhaling emissions generated by 3-dimensional (3D)-printing with polycarbonate stock

Inhalation of emissions (particulate and volatile chemicals) generated while 3-dimensional (3D) printing with polycarbonate feedstock generates respirable bisphenol A (BPA). BPA is a known endocrine disruptor that affects both reproductive and metabolic endocrine function. A previous study examining the effects of exposure to a lower dose of emissions from 3D printing (3DE, dose approximately 600 µg/m3) found changes that were consistent with other studies reporting the effects of ingesting BPA.
