Case Study

Inhalation Exposure Evaluation of Polycarbonate (PC) Filament 3D Printer Emissions

Farcas, Mariana T., et al. Journal of Toxicology and Environmental Health, Part A, 2024, 87(8), 325-341.

Ultrafine particles (UFPs) and volatile organic compounds (VOCs) are released during fused filament fabrication (FFF) 3D printing with polycarbonate (PC) filaments. This work determined the toxicity of PC filament printing emissions to rats by systemic inhalation exposure.
· Evaluation Methods
Male Sprague Dawley rats were exposed to a single concentration (0.529 mg/m 3, mean diameter 40 nm) of 3D PC filament emissions by systemic inhalation for 1, 4, 8, 15, and 30 days (4 h/day, 4 days/week). After exposure, the rats were evaluated for pulmonary and systemic responses.
· Evaluation results
The data indicate that 3D PC filament emissions did not produce significant pulmonary or systemic toxicity in rats at a relatively low systemic inhalation concentration of 0.529 mg/m3, which is inconsistent with the toxicological results observed in other in vitro studies (relatively high concentrations). Inhalation of low concentrations of PC filament emissions did not produce significant pulmonary or systemic toxicity in rats.

Impact of Recycled Polycarbonate on the Performance of 3D Printing Filaments

Gaikwad, Vaibhav, et al. ACS Sustainable Chemistry & Engineering, 2018, 6(11), 14432-14440.

This study repurposed e-waste plastics (primarily polycarbonate) into sustainable 3D printing filaments and found that their performance was comparable to virgin ABS plastics.
Key Findings
· The properties of filaments and 3D prints made from e-waste plastic were assessed in comparison to those made from virgin ABS, a commonly used polymer in 3D printing. The e-waste plastic filaments and prints demonstrated breaking and tensile strengths reaching up to 76% and 83%, respectively, of their virgin counterparts.
· The impact of recycling and repeated extrusion processing on the filaments was examined. Both virgin and e-waste plastic filaments were found to be printable for up to three processing cycles.
· Results from thermogravimetric analysis (TGA) and nuclear magnetic resonance (NMR) were utilized to develop a semiquantitative mechanism explaining the degradation of both types of filaments with an increasing number of processing and extrusion cycles.
· Life cycle assessment (LCA) studies indicate that producing 3D printing filaments from e-waste plastics reduces CO2 emissions by 28% compared to using virgin plastics.
