Since March 2018 IRT Saint-Exupéry, Toulouse’s specialist aeronautics and space research institute, has been working on the Metallic Advanced Material for Aeronautics, or MAMA, project. Taking a hybrid approach between traditional forging/stamping and additive manufacturing, the project includes the collaboration of Airbus, Aubert & Duval, LGP de l’Enit (The Laboratory of Production Engineering) and EBAM 3D printer manufacturer Sciaky.
Now the team is approximately a third of the way through the four year undertaking is has announced that MAMA is due to enter testing phases in September 2019.
Update - MAMA - Project - Progress - World
The most recent update on MAMA project progress was given at the 2019 World Titanium Conference held this week in Nantes, France. Stéphane Hollard, Head of Metals at Aubert & Duval, is MAMA project manager. At the conference, Hollard described the project’s objective as “to contribute to a significant reduction in the production costs of titanium aeronautical structures parts by developing our historical “forging / stamping transformation process [and] coupling it with additive manufacturing.”
The additive manufacturing process used in this project is Sciaky’s Electron Beam Additive Manufacturing (EBAM).
MAMA - Project - Partner - Airbus - Sciaky
MAMA project partner Airbus has had its own Sciaky EBAM 110 system in operation since December 2016, at which time it was used to build an upper spar part for an airplane wing. This machine was sold to the company by Lyonnaise additive manufacturing services and systems provider x3D Group.
