DED & SLM Processing Applications at MT Aerospace

DED (direct enery deposition) and SLM (selected laser melting) has been successfully applied at MT Aerospace. Within an ESA FLPP study, DED was optimized for propellant half shell manufacturing. Demonstrators were manufactured verifying geometry, defect and material requirements. A feasibility study performed on several aluminum alloys with DED identified limitations to several new alloys and feasible application to one AlCu alloy.

SLM is in operation at MT for both commercial and aerospace hardware including aluminum, titanium and steel alloys. Engine applications included firing test qualification. ECSS requirements qualification and certification is in progress and partly implemented. Production of fracture critical hardware in ongoing.
