In this study, metal powder filters of various shapes were manufactured using the metal extrusion additive manufacturing (MEAM) process, which is used to manufacture three-dimensional structures by extruding a filament consisting of a metal powder and a binder. Firstly, filaments were prepared by appropriately mixing SUS316 powder with sizes ranging from 7.5 µm to 50 µm and a binder. These filaments were extruded at temperatures of 100℃ to 160℃ depending on the type of filament being manufactured, to form three types of cylindrical filter. Specimens were sintered in a high vacuum atmosphere furnace at 850℃ to 1050℃ for 1 hour after debinding. The specimens were analyzed for permeability using a capillary flow porometer, porosity was determined by applying Archimedes’ law and microstructure was observed using SEM.}, type={Article}, title={Fabrication of Metal Gas Filter by Material Extrusion Additive Manufacturing Process}, URL={http://journals.pan.pl/Content/125125/PDF/AMM-2022-4-43-Jung-Yeul%20Yun.pdf}, doi={10.24425/amm.2022.141085}, keywords={Gas Filter, additive manufacturing, stainless steel, porosity, powder size}, }
