Additive manufacturing techniques have reshaped the landscape of metalabrication, revolutionizing traditional manufacturing methodologies. This comprehensive review navigates the transformative journey of additive manufacturing in metal fabrication, tracing its evolution from prototyping applications to its current status as a pivotal manufacturing paradigm. The exploration encompasses pivotal aspects, including the evolution of printing techniques, material advancements, diverse industry applications, challenges faced, and future prospects. The evolution of additive manufacturing techniques—from selective laser melting (SLM) to electron beam melting (EBM) and beyond— has facilitated the fabrication of intricate metal components with superior strength, flexibility, and customization. Materials innovation has expanded the horizon, embracing exotic alloys and refining powder metallurgy to unlock new properties and applications. Industries ranging from aerospace to healthcare, automotive to energy, have embraced additive manufacturing for lightweight, customized, and high-performance components, redefining manufacturing possibilities. However, challenges such as standardization, post-processing techniques,
scalability, and material development persist, necessitating concerted efforts for resolution. Looking ahead, future prospects lie in multimaterial printing, enhanced automation, sustainable practices, and the integration of advanced technologies, promising further innovation and widespread adoption. This review encapsulates the transformative potential of additive manufacturing in metal fabrication, underscoring its role in fostering innovation, customization, and agility across industries. As additive
manufacturing continues to evolve, it propels us toward a future where the boundaries of what’s achievable in metal fabrication are continually redefined.
