| Abstract Scope |
In metal additive manufacturing, the primary goal has been to create dense parts to compete with traditional manufacturing. With proper parameterization and characterization of a porous structure, the potential of metal additive manufacturing is expanded beyond the scope of replacing dense metal parts and allows designers to create materials with both porous and solid portions for fluid flow, wicking, and weight reduction. SS316L samples of varying hatch spacing have been printed to create vertical pore channels. Some samples with dense borders have been printed to test the solid/porous boundary. Compression, fluid flow, and capillary tests have been performed to test the properties of the structures. This research expands the uses of metal AM by characterizing porous channels and utilizing parameterization to create porous channels with a wall thickness of a single melt pool, allowing for smaller and more pores in a cross-sectional area than possible through modeling. |
