In order to convert the output volume fraction field as the result of the 3D topology optimization to TPMS infilled structures, the open-source code ASLI (A Simple Lattice Infiller) was used . The design variable of the optimization process (γ) was first mapped into a manufacturable porosity range (in this case, 10% to 90% porosity) and then was given as the input to ASLI. The resulting structure is in the format of an STL file to be fabricated using stereolithography 3D printing. ASLI discretizes the input object by converting the desired TPMS infill into a surface triangulation using the Computational Geometry Algorithms Library (CGAL) .
