Auxetic mechanical metamaterials (AMMs), as an exciting paradigm of metamaterials, have attracted increasing attention due to their interesting mechanical properties (e.g. negative Poisson's ratio), as well as the emergence of advanced manufacturing technology (e.g. 3D printing). Although various reviews on AMMs, their structures, properties, and applications, have existed, it still lacks a comprehensive review in terms of manufacturing methods. Herein, the latest progress in AMMs is extensively reviewed, including AMMs’ structures, characteristics, manufacturing methods, and applications. In addition, the current challenges and future works of AMMs are concluded and discussed. This Review aims to serve as a collection of knowledge that supplies more comprehensive understanding and inspiration to support further developments of AMMs from the perspective of design and manufacturing. Herein, the recent advancements in auxetic mechanical metamaterials (AMMs) are systematically reviewed, including AMMs’ structures, characteristics, manufacturing methods, and applications. Further, the current challenges and future works of AMMs are discussed in terms of the above aspects. This Review provides a collection of knowledge that promotes the further developments of AMMs.
