• Description:
  Three-dimensional (3D) printing is increasingly being used in manufacturing settings, homes and schools. Fused deposition modeling (FDM) 3D printers are the most widely used systems with standard thermoplastics such as acrylonitrile butadiene styrene (ABS), polylactic acid and polycarbonate (PC) commonly used in the manufacturing processes. Heating of the thermoplastic generates and releases particulates and fumes. Emission constituents frequently measured include aldehydes, benzene, toluene, ethylbenzene, and xylenes. Inhalation of the emitted particulates and/or the fumes, that contain bisphenol A (BPA) may pose health problems to users of these systems as well as bystanders. The goal of the current study was to examine the effects of inhalation of PC-emissions generated during 3D-printing. PC-emissions can include bisphenol A (BPA). Bisphenols are known endocrine and metabolic disruptors (i.e., they interfere with actions of steroid and thyroid hormones) and have been shown to have significant effects on a number of physiological systems including the endocrine and cardiovascular systems. Because steroid hormones have major effects on cardiovascular function, it is possible that inhalation of PC particulate and/or BPA impact cardiovascular function. To begin to understand how inhalation of PC-emissions generated during 3D printing might affect the cardiovascular system, the current study examined the effects of inhaling PC-emissions after 1, 4, 8, 15 and 30d of exposure, on peripheral vascular responses to vaso-modulating agents, on cardiac morphology and on the expression of proteins and transcripts that are markers of inflammation, oxidative stress and cardiovascular dysfunction.
