Design, fabrication and characterization of porous structures produced by selective laser sintering

Figure2. Relationship of porosity and characteristic length. Figure2-H: porosity and wall thickness of honeycomb structure; Figure2-D: porosity and diameter of diamond lattice structure; Figure2-P: porosity and wall thickness of Primitive TPMS structure; Figure2-G: porosity and wall thickness of Gyroid TPMS structure. Figure4. Porosity measurement. The left one of two vertical axes is the relationship of designed porosity and measured porosity while the right one is the relative error. Figure5. Relationship of porosity and compressive properties of four porous structures.
