| Abstract Scope |
This study introduces a method for fabricating porous SUS316L stainless steel using the Material Extrusion (MEX) additive manufacturing process. MEX enables the formation of fine pores with high design freedom, making it ideal for engineering porous metals. Two feedstocks with average particle sizes of 50 μm and 8 μm were used to control pore structure and mechanical properties. The 50 μm foam showed larger pores (10.3 μm), high porosity (49.55%), and excellent gas flowability, making it suitable for filtration. The 8 μm foam exhibited finer pores (1.7 μm), lower permeability, and higher compressive strength. SEM and EBSD analyses revealed differing sintering and deformation behaviors. Both foams outperformed conventional SUS316L foams in strength-to-weight ratio. These results demonstrate that MEX can produce porous structures with tunable performance, suitable for filtration and lightweight applications. |
