Additive manufacturing (AM), often referred to as 3D printing, is a transformative technology that fabricates complex components by adding material layer by layer. This review highlights the application of AM in the aerospace industry, emphasizing its precision, customization, and cost-effectiveness. The process involves design, methods, and processes, with specific attention to material selection, quality assurance, regulatory compliance, and skilled personnel. Key AM methods include stereolithography, fused deposition modeling, direct energy deposition, and powder bed fusion. Each method has unique advantages and limitations, such as material compatibility, cost, and surface finish. The review also discusses the importance of testing, standards, and certification to ensure the quality and safety of AM components. Additionally, it addresses the need for training and education to support the integration of AM in the aerospace industry. Despite the challenges, AM continues to revolutionize aerospace component manufacturing, offering innovative solutions for complex engineering challenges.Additive manufacturing (AM), often referred to as 3D printing, is a transformative technology that fabricates complex components by adding material layer by layer.
