Identification of effective control technologies for additive manufacturing

Autor: Johan du Plessis, Sonette du Preez, Aleksandr B. Stefaniak

Publikováno v: J Toxicol Environ Health B Crit Rev

Additive manufacturing (AM) refers to several types of processes that join materials to build objects, often layer-by-layer, from a computer-aided design file. Many AM processes release potentially hazardous particles and gases during printing and as

Emissions and Exposures Associated with the Use of an Inconel Powder during Directed Energy Deposition Additive Manufacturing

Autor: Plessis, Marelizé van Ree, Sonette du Preez, Johan L. du

Publikováno v: International Journal of Environmental Research and Public Health; Volume 20; Issue 13; Pages: 6206

Additive manufacturing (AM) has been linked to potential exposure-related health risks, however, there is a paucity of sufficient research. This study aimed to supply information regarding emissions and exposure during directed energy deposition (DED

Large-Format Additive Manufacturing and Machining Using High-Melt-Temperature Polymers. Part II: Characterization of Particles and Gases

Autor: Johan L. Du Plessis, Alycia K. Knepp, J.R. Wells, Andrew Bader, Jack R. Pretty, M. Abbas Virji, Matthew G. Duling, Alyson R. Fortner, Duane R. Hammond, Sonette du Preez, Stephen B. Martin, Jennifer L. Roberts, Austin Schmidt, Aleksandr B. Stefaniak, Lauren N. Bowers, Jason E. Ham

Publikováno v: J Chem Health Saf

Extrusion of high-melt-temperature polymers on large-format additive manufacturing (LFAM) machines releases particles and gases, though there is no data describing their physical and chemical characteristics. Emissions from two LFAM machines were mon
