We investigate the underlying topological constraints of cell structures and their influence on the resulting mechanism. In this paper, we establish the underlying foundations of mechanisms that are composed of cell structures—known as metamaterial mechanisms. Such metamaterial mechanisms were previously shown to implement complete mechanisms in the cell structure of a 3D printed material, without the need for assembly. However, their design is highly challenging. A mechanism consists of many cells that are interconnected and impose constraints on each other. This leads to unobvious and non-li
