Porous structure, method for manufacturing porous structure, and 3D modeling data

摘要

To provide a porous structure capable of improving durability, a method of manufacturing a porous structure capable of obtaining a porous structure capable of improving durability, and a porous structure capable of improving durability. Provide data for possible 3D modeling. A porous structure 1 of the present invention is a porous structure made of a flexible resin or rubber, and the porous structure defines a plurality of cell holes C. And a skin portion 6 which covers at least a part of the virtual outer contour surface of the skeleton portion and is integrally formed with the skeleton portion, and the skin portion has a virtual outer contour surface VC of the skeleton portion. A plurality of pillars 6C extending along the plurality of pillars, a plurality of pillar joints 6J each coupling the ends of the plurality of pillars, and a plurality of skin virtual surfaces partitioned between the plurality of pillars V6, and the skin portion has a non-uniform unit area ratio, which is a ratio of the total area of the pillar portion and the pillar joint portion within 1 cm 2.
