Review on Additive Manufacturing Process in Aircraft Industries

Abstract

This paper explores the feasibility of implementing 3D printing technology for manufacturing seat buckles in the Airbus A380. While additive manufacturing has gained attention for its versatility, safety-critical components require rigorous testing and certification. Through a comprehensive review of literature and expert interviews, this study analyzes the viability of 3D printing for seat buckle production. The results indicate that traditional manufacturing methods, such as injection molding and forging, remain the preferred choices due to their established reliability and quality control procedures. The aviation industry places the utmost importance on safety and reliability, especially in the manufacturing of safety-critical components like seat buckles. This paper examines the potential integration of 3D printing technology into the production process of seat buckles for the Airbus A380, considering the stringent certification requirements and performance expectations. A literature review encompassing additive manufacturing techniques, aerospace certification processes, and current seat buckle manufacturing practices was conducted. Expert interviews were also conducted to gather insights from industry professionals with expertise in aerospace manufacturing. The analysis revealed that conventional manufacturing methods such as injection molding and forging are currently preferred for seat buckle production in the Airbus A380 and other aircraft parts. These methods have established reliability and quality control procedures, ensuring compliance with rigorous safety standards. Although 3D printing has found success in prototyping and non-critical components, its application in safety-critical components like seat buckles is limited. The decision to favor traditional manufacturing methods for seat buckle production in the Airbus A380 is driven by the need for extensively tested and certified components. Safety-critical parts undergo stringent testing to guarantee their performance under various operating conditions. While 3D printing offers design flexibility and reduced lead times, further research and development is necessary to ensure its viability in safety-critical applications. At present, 3D printing technology is not widely employed for manufacturing seat buckles in the Airbus A380. Traditional methods provide the required reliability and quality control procedures. However, ongoing advancements in additive manufacturing may present future opportunities for incorporating 3D printing technology into safety-critical applications within the aerospace industry. Further research and development are necessary to explore these possibilities.
