This work presents the development of the additive manufacturing process of large metal components based on concentric wire laser deposition technology. This technology is recognized as of great interest by the aeronautical sector as it would allow to reduce the cost of titanium components that currently require very expensive forging and machining operations. Experimentally, the different types of failure of the deposition process are shown, as well as the different stages of the process, starting with single-weld deposition and ending with the construction of regular solid geometries. A priori, wire deposition has structural advantages compared to metal powder deposition. This work focuses on the adjustment of the process from a macroscopic and merely geometric point of view prior to the microstructural and properties analysis foreseen in future works.
