Abstract

Additive manufacturing (AM) has revolutionized industries by enabling the layer-by-layer 3D printing of objects. Among the diverse materials employed in AM, polymers and their composites hold significant importance due to their wide-ranging applications in fields such as medicine, aerospace, and automotive engineering. Extensive research efforts have been dedicated to developing advanced polymer materials tailored for various AM techniques, encompassing vat photo-polymerization, material jetting, powder bed fusion, material extrusion, binder jetting, and sheet lamination. While previous reviews often focus on specific aspects, this comprehensive review offers a holistic overview of polymer material advancements in AM. The review explores notable breakthroughs in newly developed materials and their potential applications. Furthermore, it outlines the existing challenges in utilizing AM for polymer materials and identifies promising opportunities, aiming to stimulate further progress in this dynamic and transformative field.
