Natural Fiber Reinforced Composite Materials for the Additive Manufacturing Process- A review

Abstract The use of natural fiber–reinforced composites (NFRCs) in additive manufacturing has increased due to their favorable mechanical performance and sustainable material characteristics. Various Additive techniques used for enable the production of lightweight and structurally efficient components from renewable fiber-based materials. Fibers such as kenaf and other natural reinforcements contribute to reduced environmental impact through biodegradability and resource renewability. However, challenges related to material homogeneity, interfacial bonding, and optimization of printing parameters continues to limit large-scale adoption. Despite these constraints, natural fiber-based composites demonstrate significant potential for advancing sustainable manufacturing practices and extending the output of Additive technologies. Recent developments in additive manufacturing methods are summarized in this article, with an emphasis on the addition of biodegradable fibers into matrix materials. The investigation of these materials reveals their potential uses in a number of sectors, such as building construction and automobile industry. The expanding importance of these materials in lowering environmental impact and developing additive manufacturing technologies is emphasized in the article. Overall, it offers a thorough summary of recent studies and potential paths forward in this cutting-edge area.
