Abstract: The design of porous structure is one of the main factors that affect performance. It is an important way to reduce the material mass by optimizing porous structure. Static mechanics simulation is used to analyze the change rules of different plate inner structures. Israel Objet Eden250 stereo lithography apparatus is used to solidify different structures of Vero White photosensitive resin, AG-Xplus electronic universal testing machine is used to test the compressive properties of samples, and the simulation results are compared as well. The results show that the compressive strength of porous structure reduces with the increase of porosity, and the value of different structures is in the range of 15~70MPa. The honeycomb structure has a better performance than the hexahedron structure, and the hexahedron structure has a better than the octahedron structure. The results are basically consistent with the theoretical results, which provide a theoretical and experimental basis for the successful application of porous structure in the additive manufacturing.

Key words: stereo lithography apparatus, additive manufacturing, photosensitive resin, porous structure, mechanical property
