“…Hydrogels are another polymeric smart material for 4D printing. They are hydrophilic materials but do not dissolve in water due to crosslinks between polymer chains [43], [44]. Thus, hydrogels can be submerged in water and absorb water until they reach saturation.…”

Additive Manufacturing, often known as 3D printing, is a process that uses a variety of materials to manufacture highly accurate items layer by layer. However, this technology has its limitations. One such limitation is the inability to print components larger than the printer's size due to the limited size of the build chamber. 4D additive manufacturing or 4D printing is an innovative development based on 3D printing that allows objects to be reshaped after printing, using stimuli-responsive materials that require external stimuli. This article present a review on 4D printing. Four databases, Google Scholar, ScienceDirect, IEEE Xplore, and Scopus database, were systematically searched for relevant review articles to identify and classify research studies. Specific keywords (4D printing, additive manufacturing, smart materials, stimuli, and application) were identified and used to guide the discovery of relevant studies. A total of 28 full articles were reviewed to study the applications of 4D printing, smart materials for 4D printing, as well as the effect of various stimuli on 4D printed objects. In conclusion, this review gives a summary of 4D printing and highlights its potential for revolutionizing manufacturing and further research is required to solve the limitations posed by this technology.

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.
