In recent years, 4D printing has allowed the rapid development of new concepts of multifunctional/adaptive structures. The 4D printing technology makes it possible to generate new shapes and/or property-changing capabilities by combining smart materials, multiphysics stimuli, and additive manufacturing. Hygromorphs constitute a specific class of new smart materials where their properties and morphing capabilities are dependent on the surrounding humidity, which drives actuation. Although multiple efforts have been made to fabricate hygromorph demonstrators, a comprehensive design process to produce hygromorphs by multiple 4D printing techniques is not yet available. The broad aim of this review and concept paper is to i) highlight existing scientific and technology gaps in the field of 4D-printed hygromorphs, ii) identify tools existing in other research fields for filling those gaps, and iii) discuss a series of guidelines for tackling future challenges and opportunities to develop 4D-printed composite hygromorph materials and related manufacturing processes. Accordingly, this review describes the materials and additive manufacturing techniques used for hygromorph composite fabrication. Moreover, the relevant parameters that control actuation, the models selection and performance, the design methods and the actuation measurements for customized 4D-printed hygromorph materials, are discussed.

With the growing prominence of environmental conservation awareness, there has been a notable surge in the exploration of renewable materials, particularly in the realm of natural fiber reinforced polymer composites. This heightened focus is underscored by the recent advancements in additive manufacturing techniques dedicated to continuous natural fiber reinforced composites (CNFRCs), which have inherently opened unprecedented avenues for the holistic customization of CNFRCs with meticulously tailored properties. This work reviewed the advanced techniques for 3D printing CNFRCs and addressed their challenges and perspectives in the future. First, the 3D printing processes of CNFRCs were reviewed, and the use of reinforcement and matrix phases was classified in detail. Then, CNFRCs were discussed in terms of their mechanical performances and novel function of shape‐changing. Further, performance optimization and prediction methods of 3D printed CNFRCs were discussed. In conclusion, a perspective on future study opportunities of 3D printed CNFRCs was provided from design, manufacturing, prediction to application.
