Potential Hazards of Additive Manufacturing

Additive manufacturing (AM), commonly referred to as 3-D printing, is becoming more prevalent in industry. AM is a set of processes for making products by selectively joining small amounts of material, using a computer-aided design file. [1,2] The advantages for industry include: shortened production cycles, reduced tooling costs, reduced waste material, easier product customization, novel design options, and new possibilities in distribution and fulfilment. [2–6] The automotive, aerospace, medical device, and electronics manufacturing industries are already using AM, and biomedical applications are expected to grow. Additionally, AM is found in construction, offices, and libraries. It is also important to note the rapid rise of AM in schools, including K–12, as a teaching tool for advanced design and manufacturing technologies.

Though progress has been made in understanding exposures and risks in this field, there is still a need for research on the potential health and safety implications for workers. A new paper from NIOSH researchers, “Potential Occupational Hazards of Additive Manufacturing” published in the Journal of Occupational and Environmental Hygiene highlights AM processes, identifies potential hazards, and discusses research needs for protecting workers.
