When manufacturing components from forged blanks of nickel-based super alloys, companies have to cope with rising prices, long delivery time as well as cost intense machining. In this case Additive Manufacturing (AM) can provide an alternative solution. To prove the feasibility of AM, an aircraft engine mounting component was successfully built up by Laser Material Deposition (LMD) from Inconel 718 powder. Due to the length of 500 mm and its complex structure, the pylon bracket component is demanding to build up by LMD. Investigations on process and buildup strategy development as well as analysis of deformation behaviour have been performed.
