Figure 7.

(a) Illustration of how sheet-based and ligament-based TPMS lattices can be designed, implicitly, along with plots that show the relationship between the parameters t and c, and relative density and surface area-to-volume ratio for selected TPMS lattice types, respectively. (b) Demonstration of the printability of these intricate structures using polymer-based additive manufacturing process and base material. Illustration of; (i) how sheet-based and ligament/solid-based TPMS architectures are constructred through implicity strategies, (ii) relationship between surface area-to-volume ratio of unit-cell sheet-based TPMS with variation in level-set parameter, (iii,iv) relationship between relative density and arbitrary parameter for sheet-based and ligament/solid-based TPMS architectures, respectively.
