Introduction

The rapid development in additive manufacturing (AM) technologies have enabled the creation of mechanical metamaterials across all length scales, which are an emerging class of man-made materials that derive benefits from their rationally designed geometries along with the intrinsic properties of their constituents from extreme manufacturing. To date, mechanical metamaterials have demonstrated their ability to unlock unique properties and behaviours not observed in nature or other conventional materials, such as ultrahigh strength-to-density ratios, extraordinary resilience from brittle constituents, precisely controlled shape transformation, and tunable multifunctional properties. Such properties have led to performance breakthroughs across a wide range of applications, including lightweight structures, flexible electronics, soft robotics, energy harvesting and storage devices, etc.

Yet, to translate the unique features of mechanical metamaterials into practical applications, new advances in extreme manufacturing are crucial. This may include enhancing the build volume and/or resolution of AM processes, implementation of advanced post-processing methods, development of new compositions (e.g., polymers, hydrogels, metals, ceramics, carbon, composites), testing and characterization under extreme conditions, as well as novel devices and applications.   

The aim of this special issue is to provide a forum for researchers to present and review the state-of-the-art development, challenges, and insights on multiscale manufacturing of mechanical metamaterials, with an emphasis on structure design, fabrication process, microstructural, mechanical, multifunctional characterization, as well as recent progresses in functional applications.
