Figure 1, reproduced from [1]. Photolithographic techniques are used to pattern a metal layer and metal is evaporated in that pattern on top of a sacrificial layer. The metal template is then dip-cast in solder. Finally, the sacrificial layer is removed and the metal template with solder is heated, and it self-assembles into the minimal free-energy polyhedron.
