The development of metal–polymer composites represents a pivotal advancement in the field of additive manufacturing (AM), offering new pathways for high-performance, multifunctional materials that can address the limitations of single component systems [1]. These composites combine the desirable properties of metals—such as strength, stiffness, electrical conductivity, and thermal stability—with the versatile attributes of polymers, including low density, corrosion resistance, design flexibility, and biocompatibility. The resulting hybrid materials exhibit a balance of structural robustness and functional adaptability that makes them highly attractive for next-generation applications in sectors such as biomedical engineering, aerospace, automotive, defense, and structural electronics [2].
