Additive manufacturing (AM) has revolutionized the aerospace industry by enabling the production of lightweight, complex components that traditional manufacturing methods cannot achieve. This paper explores the advancements in AM technologies and their application in creating lightweight materials for aerospace applications. We examine various AM techniques, including Selective Laser Melting (SLM), Electron Beam Melting (EBM), and Cold Spray Additive Manufacturing, focusing on their ability to fabricate components with reduced weight without compromising structural integrity. The integration of lightweight materials such as titanium alloys, aluminum, and composite foams into AM processes is discussed, highlighting their impact on fuel efficiency and overall performance. Furthermore, the challenges associated with AM in aerospace, including material properties, process optimization, and certification, are addressed. The paper concludes by emphasizing the potential of AM to transform aerospace manufacturing, offering insights into future research directions and technological advancements.
