This review delves into four‐dimensional printing (4DP) through fused filament fabrication (FFF) and its implications for human‐material interaction (HMI). FFF 4DP’s emergence in HMI represents a nascent and evolving concept worthy of deeper exploration. The article introduces FFF 4DP’s fundamental principles, methodologies, materials, and associated benefits and challenges. Its primary focus is the intersection between FFF 4DP and HMI, investigating the potential of employing FFF 4D printed objects as interactive interfaces. Various HMI scenarios are examined, including applications in soft actuators, smart toys, household devices, smart consumer products, 4D textiles, and customizable wood‐based items. Moreover, the article discusses the current state‐of‐art and development in the field, highlighting notable projects that integrate FFF 4DP into HMI to advance environmental sustainability. It also identifies key challenges/limitations requiring attention for the widespread adoption of 4DP in HMI applications. This work offers an in‐depth analysis of FFF 4DP within the HMI context, underscoring its potential to transform human interactions with machines and smart devices. It introduces innovative features for dynamic and adaptable interfaces, promising to revolutionize user experiences. The article serves as a valuable resource for researchers, practitioners, and designers interested in exploring the exciting possibilities of FFF 4DP in the realm of HMI.This article is protected by copyright.

“…Such understandings of the relationship between the phenomena and the geometry, the materials and the process behaviours, are valuable for designing components with arbitrary shapes and complexities. Beyond FEA, new simulation methods involving machine learning [116][117][118], topology optimization [119], and inverse-design algorithm [120] can also be developed to predict and construct a targeted 3D morphed geometry. For example, topology optimization was used as a powerful digital tool to optimize architectures with more functionalities [119].…”

4D printing allows for the transformation capabilities of 3D-printed architectures over time, altering their shape, properties, or function when exposed to external stimuli. This interdisciplinary technology endows the 3D architectures with unique functionalities, which has generated excitement in diverse research fields, such as soft robotics, biomimetics, biomedical devices, and sensors. Understanding the selection of the material, architectural designs, and employed stimuli is crucial to unlocking the potential of smart customization with 4D printing. This review summarizes recent significant developments in 4D printing and establishes links between smart materials, 3D printing techniques, programmable structures, diversiform stimulus, and new functionalities for multidisciplinary applications. We start by introducing the advanced features of 4D printing and the key technological roadmap for its implementation. We then place considerable emphasis on printable smart materials and structural designs, as well as general approaches to designing programmable structures. We also review stimulus designs in smart materials and their associated stimulus-responsive mechanisms. Finally, we discuss new functionalities of 4D printing for potential applications and further development directions.

“…Lattices structures are one of the most versatile types of architected actuators. [27,99,152] Assembly of beams made of glass fiber reinforced elastomers differing by their filler and amount of cross-linking amount were shown to achieve large ranges of actuation authority. [99] Finally, one of the most flexible shapes to print and deform is a line.…”

“…Due to their versatility, FEA approaches are also the primary choice for design. A recent example of how FEA can be used to design actuators with accurate and rapid simulations is the isogeometry approach developed by Yu et al [152] This technique aims at mixing the benefit of graphical design and FEA tools by fitting the mesh efficiently on complex geometries. Yu et al have associated this model with a random forest machine learning regressor for each vertex positioned on the grid structure initially designed.…”

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.
