Résumé

Lattice structure is critical for designing light-weight or multi-function components in additive manufacturing. A lot of know-how had been accumulated via the benchmarking of cellular units. However, how to optimize the parameters and the topological distribution of lattice cells in a constrained design space to gain both mass and computation efficiency for structure design is still an open question. To answer it, this paper proposes a new optimization method using design of experiment and surrogate model to configure lattice structures in specified 3D hulls. A design case is presented to show the advantages of the proposed solution. (C) 2019 Published by Elsevier Ltd on behalf of CIRP.
