Airbus: Additive manufacturing for the A350 cabin door

3D printing components are increasingly being used in aviation. Learn how Airbus can offer an ever more economical and environmentally friendly aircraft through additive manufacturing.


Aircraft manufacturers are always on the lookout for ways to make their machines more efficient. Such efficiency gains have been achieved with the A350 through the use of additive manufacturing for door locking.

The locking axles for the A350 passenger doors are made of titanium with the EOS M 400-4. Thanks to the cooperation with EOS GmbH, Airbus was able to benefit significantly from the many advantages offered by 3D printing.

Cost-efficient additive production of flight-critical locking axes for aircraft doors helps Airbus to offer an even more economical and environmentally friendly aircraft.

The additive production of locking axles for aircraft doors enables significant weight reductions, thus reducing fuel consumption and CO2 emissions.



• 45% weight reduction of AM part while remaining as sturdy as the conventional component
• 25% saving on manufacturing cost due to material savings and assembly time reduction
• Component reduction from 10 to 1
16 latch shafts are used for one A350 airplane and lead to a saving of just over four kilos
