USAAugust 24 2020. In order to assess the health risks and potential exposures of using a 3D printer in an occupational setting, a recent case study focused on determining the concentrations of NIOSH[2023]. Approaches to safe 3D printing: a guide for makerspace users, schools, libraries, and small businesses. By Hodson L, Dunn KL, Dunn KH, Glassford E, Hammond D, Roth G. Cincinnati, OH: U.S. Department of Health and Human Services, Centers for Disease Control and Prevention, National Institute for Occupational Safety The3D printing process itself liberates toxic fumes as well as particles into the air, making it very important to regularly ventilate the area and not cohabitate with a working 3D Health& Safety Concerns with FDM Printing. With regards to FDM printing, the primary health concern is that some of the filaments, when heated and used in printing 3D models, produce fumes that contain toxic substances.(ABS (Acrylonitrile Butadiene Styrene) in particular, but PLA (PolyLactic Acid), to a lesser extent, as well) Using3D-printed NP swabs to collect nasal samples for COVID-19 testing is feasible, acceptable, and convenient for local production . The FDA classified 3D-printed NP swabs as a Class I, 510(k) Exempt in vitro diagnostic medical device . Formlabs, a 3D printer manufacturer and technology developer, has used its printers to manufacture up Themost common types of 3D printing materials are thermoplastics, which are heated and extruded through a nozzle to form layers. The most popular thermoplastics are PLA (polylactic acid) and ABS 3Dprinting is gaining traction in research and development as a way to quickly, cheaply, and easily manufacture polydimethylsiloxane (PDMS) molds. The most commonly used method is resin printing, which is relatively expensive and requires specialized printers. This study shows that polylactic acid (PLA) filament printing is a Tounderstand the potential health and safety risks, NIOSH has evaluated emissions from different printer and feedstock combinations operating in chamber studies and workplace The most commonly used types of 3D printer media are PLA, ABS, and nylon. PLA is ygw8aO.
