In the past decade, mechanical metamaterials have garnered increasing attention owing to
its novel design principles which combine the concept of hierarchical architecture with …

In nature, cellular materials exhibit enhanced multifunctionalities driven mainly by their
sophisticated topologies and length scales. These natural systems have inspired the …

Cellular structures are made up of an interconnected network of plates, struts, or small unit
cells and acquire many unique benefits such as, high strength-to-weight ratio, excellent …

Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD)
virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography …

Mechanical metamaterials are man-made structures with counterintuitive mechanical
properties that originate in the geometry of their unit cell instead of the properties of each …

The extremely high melting point of many ceramics adds challenges to additive
manufacturing as compared with metals and polymers. Because ceramics cannot be cast or …

Abstract In 1903, Alexander Graham Bell developed a design principle to generate
lightweight, mechanically robust lattice structures based on triangular cells; this has since …

The mechanical properties of ordinary materials degrade substantially with reduced density
because their structural elements bend under applied load. We report a class of …

The strength of lightweight mechanical metamaterials, which aim to exploit material-
strengthening size effects by their microscale lattice structure, has been limited by the …

Additive manufacturing enables fabrication of materials with intricate cellular architecture,
whereby progress in 3D printing techniques is increasing the possible configurations of …
