Abstract

4D printing has revolutionized additive manufacturing by enabling the creation of programmable structures that respond to external stimuli. This article analyzes recent advances and key challenges in the fabrication of smart materials using fiber-reinforced thermoplastic composites (FRTPs). Computational modeling approaches such as Finite Element Analysis (FEA), Isogeometric Analysis (IGA), and hybrid techniques incorporating machine learning (ML) are reviewed to enhance simulation accuracy. Additionally, manufacturing challenges, including optimization of printing parameters, fiber-matrix adhesion, and sustainability through the use of recycled thermoplastics, are discussed. Finally, research opportunities are identified to improve the scalability and performance of these materials in industrial applications such as aerospace, biomedical, and robotics.
