General design flow of a gyroid structure fabrication using Markforged® Mark Two printer: (a) a sheet-based gyroid unit-cell; (b) matrix of the gyroid; and (c) fiber-reinforcement inside the matrix of the gyroid Refer to the image caption for details.The illustration presents three stages of lattice structure development based on a sheet-based unit cell. Panel A shows a single 1 multiplied by 1 unit cell with curved interconnected surfaces and dimensions of 20 millimetres along each side. X, Y, and Z coordinate directions are indicated beneath the structure. Panel B displays a larger 2 multiplied by 2 unit cell arrangement formed by repeating the original geometry into a porous three-dimensional lattice. Panel C presents a modified 2 multiplied by 2 unit cell with additional irregular internal features and textured surfaces integrated into the lattice architecture. Arrows indicate the transformation sequence between structural stages.
