Airline MRO receives first approval to 3D print aircraft parts using EOS powder-bed fusion technology

Etihad Engineering unveils 3D printing laboratory

Etihad Aviation Group’s MRO division, Etihad Engineering, has collaborated with leading 3D printing technology providers to open the region’s first approved additive manufacturing facility.

The facility has been opened in collaboration with 3D specialists EOS and BigRep and has gained Design and Production Approval from the European Aviation Safety Agency (EASA).

The laboratory is located at the Etihad Engineering facility adjacent to Abu Dhabi International Airport and features two approved industrial 3D printers. Its primary machine is the powder-bed fusion technology system EOS P 396, for demanding high performance and high quality aircraft applications. The system enables faster production and reduced weight of cabin parts, in contrast to traditional manufacturing processes.

New facility positions Etihad Engineering as “pioneer in innovation and technology”

Etihad Engineering, together with its partner EOS, received one of the first Airline MRO approvals from EASA for 3D printing using powder-bed fusion technology which will be used to design, produce and certify additively manufactured parts for the aircraft cabin of the future.

Bernhard Randerath, VP Design, Engineering and Innovation, Etihad Engineering, said: “The launch of the new facility is in line with Etihad Engineering’s position as a leading global player in aircraft engineering as well as a pioneer in innovation and technology. We are extremely proud to collaborate with EOS and BigRep to expand our capability and support the UAE’s strategy to increase production technology and cement its position as a global aerospace hub.”

Additive manufacture will address "key challenges" in aerospace industry 

Markus Glasser, Senior Vice President, Export Region, EOS, said: “Being committed to high quality solutions and constant technology innovation, Etihad Engineering and EOS share the same mindset. Together, we want to bring the design and production of aircraft interior parts to the next level.” 

Glasser added: “Producing cabin interior parts additively will offer a substantial value-add in terms of optimised repair, lightweight design, shorter lead times and customisation, addressing some of the key challenges of the aerospace industry.”

The EOS-installed system produces serial parts from polymer materials such as PA 2241 FR, and enables the manufacture of cabin parts for an aircraft’s heavy maintenance C-Check. Cabin defects can also be rectified within a short turnaround time which allows for the production of the required cabin parts during line maintenance.

The EOS machine operates with a total build volume of 340x340x600mm. The modular system enables the tool-free manufacture of serial components, spare parts, functional prototypes and models directly from CAD data.

The second machine, BigRep ONE, is one of the largest, serial-built industrial thermoplastic extrusion 3D printers. Bringing additive manufacturing to MRO, ONE is designed for manufacturing on-site and on demand of large parts, jigs and fixtures as well as moulds.

Developing the full potential of additive manufacturing

“Our 3D printers have established 3D printing and additive manufacturing (AM) as an innovative, added-value technology in the aviation industry. They offer an unprecedented level of precision, quality and speed, and enable us to use the high-performance, innovative printing materials the aviation industry requires,” said Martin Back, BigRep Managing Director.

“Together with Etihad Engineering, we will develop the full potential of AM. In the next phase, a BigRep PRO, the most advanced large-format FFF 3D printer will be installed.”

The facility was officially opened in a ceremony attended by His Excellency Ernst Peter Fischer, German Ambassador to the UAE in recognition of the relationship between the German companies EOS and BigRep and the UAE’s Etihad Engineering.

Etihad Engineering first received EASA approval to 3D print with filament technology in 2017 and was the first airline MRO in the world to certify, print and fly 3D printed cabin parts. The latest approval, received in October 2019 covers powder bed fusion 3D printing technology.
