Ultrafine particle emissions from desktop 3D printers

Carlos Garcia Pando's curator insight, July 26, 2013 10:39 AM

The development of low-cost desktop versions of three-dimensional (3D) printers has made these devices widely accessible for rapid prototyping and small-scale manufacturing in home and office settings. Because most of these devices are currently sold as standalone devices without any exhaust ventilation or filtration accessories, results herein suggest caution should be used when operating in inadequately ventilated or unfiltered indoor environments.

The process of heated thermoplastic extrusion and deposition has been shown to have significant aerosol emissions in industrial environments, but there is no data on particle emissions from commercially available desktop 3D printers.

 Estimates of emission rates of total UFPs were large, ranging from ∼2.0 × 1010 # min−1 for a 3D printer utilizing a polylactic acid (PLA) feedstock to ∼1.9 × 1011 # min−1 for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) thermoplastic feedstock.
