Cleaning as high-risk activity for respiratory particulate exposure during additive manufacturing of sand moulds and its preceding silica sand coating process

Occupational exposure to respirable crystalline silica (RCS) is a known cause of respiratory diseases, such as silicosis and lung cancer. Binder jetting additive manufacturing (AM) uses silica sand coated with sulphonic acid as feedstock material and operators are potentially exposed to RCS during v...
