3D printing or additive manufacturing allows users to “print” a variety of items, from airplane parts to prosthetic limbs. 3D printing is still a relatively new technology and there are many gaps in the information available about health and safety implications. As with many innovations, workers are the first groups exposed to potential hazards.
Engineered nanomaterials are materials that are intentionally produced and have at least one primary dimension less than 100 nanometers (nm). Nanomaterials have properties different from those of larger particles of the same material, making them unique and desirable for specific product applications. The consumer products market currently has more than 1,000 nanomaterial-containing products including makeup, sunscreen, food storage products, appliances, clothing, electronics, computers, sporting goods, and coatings [WWICS 2011].
