Paragraph starter

Metal additive manufacturing (AM) presents significant opportunities for the aerospace industry, enabling the creation of complex, lightweight, and highly functional components. However, the transition from prototyping and specialized production to mass manufacturing is currently impeded by several critical factors. These include the ongoing development and universal adoption of industry-wide standards and qualification processes, the need for more sustainable manufacturing practices within AM, and the establishment of robust, integrated supply chains. Therefore, while AM offers design freedom, its widespread application for mass production in aerospace requires continued advancements in these key areas.
