Satair produces the first certified 3D printed metal flying spare part for Airbus

Satair, an Airbus services company, recently provided one of its airline customers with one of, if not the first, certified 3D printed metal flying spare part in the world. The part is actually a wingtip fence for an A320ceo aircraft that was no longer procurable from the original supplier. By using metal additive manufacturing to replace it, the company was able to reduce the likelihood of the aircraft being grounded. On a larger level, this operation showcases the increased flexibility in part production thanks to 3D printing technologies, all the while meeting the same high-quality standards ensured by the EASA Form1 certification. They estimate that costs were reduced by 45% making it a cheaper solution for customers and with a shorter lead-time.

For some context, the services company is a standalone Airbus subsidiary and part of the Airbus Services unit. Satair operates in 10 locations worldwide and employs over 1,300 employees to support the lifecycle of Airbus aircraft with a full and integrated portfolio of flexible, value-adding material management products, services and tailored support modules. Before jumping to 3D printing, the company studied various alternatives, including conventional manufacturing methods.

So why select additive manufacturing?

The part in question – an A320ceo wingtip fence – exists in four versions: starboard, port, upper and lower. In this case, the parts supplier could not provide the cast part anymore, leading to a natural loss of the moulds used to create these parts and resulting in a potentially high investment cost for Satair to replace the moulds for individual orders. After studying other conventional options such as re-designing the part for machining technology, the resulting cost and lead-time implications were not competitive. One of the benefits of additive manufacturing of course is the flexibility and increased freedom when it comes to manufacturing unique parts, with no need to invest in an expensive mould.
