Additive manufacturing methods facilitate the production of complex cellular materials. Commonly, their designs are based on primitive solids using linear struts without curvature continuous joints which results in notch stress. This study presents cellular material units with biomorphic features. The employed method allows us to design lattices with geometrical optimization and varying lattice morphology. The compression test results show that this method allows us to achieve a spectrum of mechanical properties for improving existing 3D printed lattice materials.
