6 pagesDate: April 3, 2024


Porous structures are widely utilized as functional components in multiple industries due to their excellent comprehensive properties. Compared with traditional production processes, 3D printing additive manufacturing exhibits a dominant advantage in flexibility and low expense for fabricating porous structures. However, the complicated geometric morphologies that are constituted by thin-walled elements decrease the mechanical performance of structures due to manufacturing issues. For this reason, a co-optimization method is proposed for designing and manufacturing graded-density porous structures. Manufacturing constraints related to the filling path are incorporated in the structural optimization. The material layout is optimized by graded-density Voronoi elements mapped by Young’s modulus. Finally, the structure is filled by an evenly continuous path without any intersection based on Voronoi skeletons. This research provides a novel idea to enhance the stiffness and promote the integration of material-structure-performance for additive manufacturing porous structures.
