This study focuses on modeling, 3D printing, and evaluating the mechanical properties of porous structures based on minimal surfaces: Schwarz P, diamond, and gyroid. Due to their exceptional geometric and mechanical properties, these structures have high potential in industrial and medical applications. In this study, the desired surfaces were modeled using mathematical equations in MATLAB, and the resulting STL file was transferred to CAD software to complete the modeling process. This procedure can be easily implemented using basic and commonly available software. The created structures were then fabricated using the FDM 3D printing method, and their mechanical properties were evaluated through quasi-static compression testing in accordance with ASTM D695 standards. The results indicated that the Schwarz P structure exhibited greater resistance to compressive loading compared to the gyroid and diamond structures in such a way that the force tolerated by this structure at some strains was about 75 percent and the total energy absorbed at the end of the compression test was about 40 percent higher than the other two structures. The innovation of this research lies in introducing a simple and practical method for accurately modeling complex minimal surfaces and evaluating the mechanical properties of porous structures using widely accessible tools. This method can significantly contribute to improving design and manufacturing processes in various industries.
