Additive manufacturing (AM) had a significant influence on the geometry design of products. It became possible to replace the full solid material with cellular structures for the optimal design of AM parts. Various types of cellular structures have been developed and studied for different purposes. However, many studies have focused on an optimal design using cellular structures having near-isotropic properties, such as cube or honeycomb structures. This paper presents the effect of the anisotropic material property on the optimal design by generating cellular structure with anisotropic material property induced by internal void geometry. Kriging metamodel-based material property model is proposed for modeling anisotropy induced by the rotation of internal void. This material model is then applied to the optimal design process. Three types of void geometry, circular, non-rotating, and rotating elliptical void, are considered to demonstrate the effect of anisotropic cellular structure on the optimal design. Due to the anisotropy induced by complex internal void geometry, Kriging metamodel-based material property models are utilized as the material property model. The effect of the anisotropic property and the material property model on the optimized structures is confirmed through two numerical examples in the perspectives of structure performance and density distribution.
