Studies Suggest 3D Printing Could Be Toxic

Researchers said manufacturers and regulators should help mitigate potential health risks. Dec 16th, 2020 iStock Manufacturers, regulators and consumers should take steps to address potential risks related to 3D printing as the technology improves and becomes more widespread, researchers suggested Tuesday. The Society for Risk Analysis’ annual meeting, held virtually this week, featured a symposium on recent studies evaluating the risks posed by 3D printing systems and products. Researchers noted that particles produced during the printing process can infiltrate the lungs, and that in addition to labs and factories, printers are frequently used in schools, libraries and homes. Researchers added that 3D printers can use potentially harmful substances including thermoplastics, metals, and volatile and semi-volatile organic chemicals processed over the course of several hours.

NIOSH: Respirator valves can control disease sources

Filtering facepiece respirators (FFRs) with exhalation valves, as well as a surgical mask or an unregulated face covering, can reduce a wearer’s aerosol emissions, according to a report released on December 9 by the National Institute for Occupational Safety and Health (NIOSH). With modifications, the respirators can offer the same level of source control as FFRs without exhalation valves. Compared with other workers and the general public, healthcare workers have faced a greater risk and a longer duration of exposure during the COVID-19 pandemic. Healthcare workers have used FFRs extensively, when available, during the pandemic.
