Abstract
Prototypes, tools and industrial components are more and more produced by additive manufacturing, which is also known as 3D printing. For this reason, the Fede-ral Institute for Occupational Safety and Health (BAuA) investi-gated workers´ exposure to hazardous substances which origi-nate from the raw materials or may result e.g. as decompo-sition products such as volatile organic compounds (VOCs). The investigation program was focussed on additive manufacturing using powder-bed processes. Workplace measure-ments took place in ten enterprises. Most of them used metal-lic alloy powders and to a lesser extent polymer powders. Both, personal air sampling and stationary sampling was per-formed. Primarily, exposure to the respirable and inhalable particle fraction and their constituents has been measured. With the exception of one polymer powders processing enter-prise, the occupational exposure limit values (OELVs) for both, the inhalable and the respirable particle fraction were adhered to. In some cases, exceedings of the assessment criteria for metals and their compounds as constituents of the released dust have been observed during processing of metal alloy powders. Based on the results of the investigation and the observed working conditions in the enterprises, recommenda-tions have been derived to ensure safe handling of hazardous substances during additive manufacturing.
