CFM Leap multi-sourcing all engine parts - Mecachrome Mecachrome is one of the suppliers of TiAl blades for the LEAP engine. I haven't found what technology(s) Mecachrome uses to manufacture the LEAP blades. Mecachrome does have good experience with EBM production.
I then remembered that I had looked to see how much Mecachrome was involved with Arcam and EBM. I didn't find much at the time. IH123's link to the FastEBM project doesn't work now. It did then. This link to the FASTEBM project still works. MECACHROME FRANCE SAS is listed as a partner.
I've looked again to see if and how Mecachrome has experience with EBM.
ASTRIUM Space Transportation has been manufacturing composite equipments for satellite for 25 years. For this business, the development of Additive Layer Manufacturing (ALM) processes has been identified as a real opportunity to improve design and performances. For satellite equipments, ASTRIUM ST has chosen to investigate in the Electron Beam Melting process (patented EBM® process from Arcam AB company) for the manufacturing of Titanium parts, in collaboration with MECACHROME who has developed strong skills in this ALM process. This first development step has been achieved by introducing a titanium part realised by EBM on an equipment of Atlantic Bird 7 satellite launched in September 2011. The new step consists in the formal industrialisation of the EBM process for the procurement of titanium parts for satellite equipments. The present paper describes the logic retained for this industrialisation. It includes the technical requirements but also the verifications and inspections which have to be performed to guarantee that technical requirements are met.
