Topological interlocking of building blocks as a materials design principle was previously shown to provide inherently brittle materials with a remarkable flexural compliance and fracture toughness. After a brief introduction to this design concept we will present materials that combine topological interlocking of discrete hard building blocks with a soft phase, thus mimicking the basic architecture of nacre. Mechanical properties of such systems, realised through 3D printing, will be discussed. A further subject that will be discussed in the presentation is introduction of metallic or polymer-based shape memory elements that provide topological interlocking structures with responsiveness to external stimuli, such as heat or electric current.
