 ADDITIVE MANUFACTURING COMES INTO ITS OWN
Like the 3D printers now well known to the general public, industry has its own additive manufacturing (AM) machines that use a digital model to build up parts in successive layers from a raw material (metallic or ceramic powder, polymers, etc.). Safran has already certified parts based on this new process, especially for the LEAP turbofan and Arrano turboshaft engines. Additive manufacturing also paves the way for the design and fabrication of highly innovative products that would be impossible to make with conventional processes. AM is both fast and flexible, but it offers other advantages as well: certain engine parts made this way are 25% lighter, while the weight of some hydraulic parts can be reduced by more than 50%. In turn, this reduces fuel consumption and improves our carbon footprint. Additive manufacturing is applied in an increasing number of industries, changing the landscape for both production and repairs. Safran has made the investments needed to accelerate the
development of this technology, in preparation for its widespread use. In particular, it has created the Safran Additive Manufacturing Campus in Le Haillan (Bordeaux region) to group all related activities: R&T, design and production.

 RETHINKING CABIN LAYOUTS
■ Safran is ideally positioned to offer cabin components that reduce overall weight: seats, partitions, luggage bins, galleys, lavatories, in-flight entertainment systems and much more. The technological synergies between Safran Cabin and Safran Seats mean that products can be very highly integrated, based on lighter state-of-the-art materials such as organic matrix composites. These innovative developments also enhance airlines’ operational efficiency, including optimized management of consumables, reduced waste and improved wastewater management.
