Abstract
Hard biological materials such as bones have evolved for millions of years, enabling them to overcome the conflict between different types of mechanical properties. The key to their success lies in the combination of limited material ingredients and mechanistic ingredients, which form of a puzzle. The fundamental features of bones are explored under a ‘voxel-by-voxel’ approach using advanced multi-material 3D printing techniques, various combinations of gradients, multilevel hierarchy, and brick-and-mortar arrangements.
