| Abstract Scope |
As 3D printers become more common in homes and workspaces, the potential health risks associated with their emissions are often overlooked. One-inch cubes were printed under varying nozzle temperatures to analyze release and duration of airborne Volatile Organic Compounds (VOC) and Particulate Matter Concentration (PMC) using a Bambu Lab X1C FDM 3D printer and Polyethylene Terephthalate Glycol (PETG), Polylactic Acid (PLA), Thermoplastic Polyurethane (TPU), and Acrylonitrile Butadiene Styrene (ABS) filaments. Emissions were monitored using two separate sets of air quality sensors inside and outside of the printer. PMC levels varied depending on nozzle temperature and material type, with the highest concentrations occurring at the start of each print. Preliminary results show that between PETG, PLA, and TPU, PETG had the highest PMC while TPU’s emissions were low; VOC did not vary significantly between materials. These findings highlight the importance of ventilation and exposure awareness when using 3D printers indoors. |
