NIOSH recently published two new posters that describe potential hazards and work activities that can cause exposure while 3D printing with both filaments () and metal powders (). The posters also suggest the engineering controls, administrative controls, and personal protective equipment that can be used to prevent exposure during different stages of 3D printing. The posters identify the hazards of 3D printing with both materials, the potential health effects, and the activities that can put workers at risk during each stage of the printing process. NIOSH’s posters then suggest different controls that can be used (for example, employing local exhaust ventilation and cleaning work areas frequently) and the PPE that workers can wear to reduce their chance of experiencing health issues. According to NIOSH, options for PPE include lab coats or coveralls; safety glasses, goggles, or face shields; and nitrile or chemical-resistant gloves.
