Welcome back! Today, we have some exciting news from Saab, where they have achieved a remarkable milestone in the world of aerospace. For the first time ever, an exterior 3D printed part has taken to the skies on a Gripen fighter jet. This part isn’t hidden inside the aircraft; it’s an actual body panel on the exterior.
A Test of Pioneering Significance
Saab’s recent triumph is a testament to their commitment to innovation. The purpose of this groundbreaking trial was to explore how additive manufacturing could revolutionize battlefield damage repair. The test flight was conducted above Saab’s facilities in Sweden on March 19th, 2023. The star of the show was the Gripen fighter jet, equipped with a replacement hatch crafted through Selective Laser Sintering (SLS) 3D printing. The material of choice? Nylon polymer, specifically, PA2200.
This achievement signifies a giant leap toward using 3D printed spare parts for rapid in-the-field repairs of fighter aircraft that have sustained damage during remote operations. In essence, it’s all about saving valuable time, a crucial advantage in such scenarios.
A Unique Approach to Spare Parts
One of the remarkable aspects of this trial was the absence of a 3D computer model for the original hatch. What did they do? The original hatch was removed from the aircraft, scanned using a 3D scanner, and a precise copy was created. This copy was then 3D printed, tailor-made to fit the specific aircraft it belonged to.
The results? Exceptional. The post-flight inspection of the hatch revealed no structural changes after the flight. This approach opens the doors to providing field maintenance personnel with individually fitted spare parts. No longer will they have to resort to emergency fixes or cannibalize other aircraft for parts. This will significantly reduce the number of parts required during deployments and minimize operational downtime during repairs.
Game-Changing Potential
Saab’s successful flight test of a 3D printed component with operational significance is a momentous step. Every part of an aircraft must meet stringent airworthiness requirements, and this achievement paves the way for increasing operational availability in the field. Additive manufacturing is set to be a game changer in this regard.
It’s worth noting that Saab’s journey with 3D printing started long before this flight test. They have been deploying the technology for over five years to create numerous internal parts for their aircraft. Collaborating closely with GKN Aerospace, they have certified flight-ready components and developed Powder Bed Fusion (PBF) processes and various materials, effectively reducing costs and lead times during aerospace production.
