To overcome the difficulty in directly predicting the mechanical properties in porous structure designing,this paper establishes a relationship model between the structural parameters and the mechanical properties of the Schwarz_P structure,by selecting the Schwarz_P surface in the triply periodic minimal surfaces,applying selective laser melting technology to manufacture the Schwarz_P structures with different structural parameters and conducting compression test for the study of Schwarz_P structures'mechanical properties.The test results show that the goodness of fit for the designed model is more than 98％,the mechanical properties predicted by the model are basically consistent with the measured values,and the mechanical properties can be intuitively predicted when designing porous structure.
