Additive manufacturing (3D printing) has emerged as a transformative technology for fabricating lightweight, geometrically complex, and multifunctional polymer components for aerospace, automotive, energy, and electronics applications. Among various nanofillers, graphene has attracted significant attention owing to its exceptional mechanical, thermal, electrical, and barrier properties, making it an ideal reinforcement for high-performance 3D-printable polymer nanocomposites [1], [2]. Recent advances in feedstock preparation, processing strategies, and printing technologies have enabled improved graphene incorporation into thermoplastic matrices, allowing tailored material performance for diverse engineering applications [3], [4]. However, challenges related to graphene dispersion, interfacial adhesion, printability, and process-structure-property relationships continue to limit widespread adoption. This work presents recent developments in graphene-reinforced polymer nanocomposites for additive manufacturing, emphasizing scalable feedstock preparation, processing considerations, and multifunctional properties. It also highlights emerging strategies and identifies key scientific and technological challenges that must be addressed to accelerate industrial implementation of high-performance 3D-printed graphene nanocomposites. |
