Demonstration of the unit cell wall thickness values of the software-generated design (left) and the printed specimens (right) for Gyroid sheet-based TPMS lattice at relative densities of (a) 13%, (b) 18%, (c) 25%, and (d) 35%. The wall thickness images and measurements on the actual specimens were conducted using Alicona InifiniteFocus optical surface roughness measuring device.
