After months of research and development, the R&D department of the U.N.S. company, part of the Emergy Group, has successfully generated metal geometries in Inconel 719 and AISI 304 by melting metal wire using a high-power laser. These geometries are then sent to solubilization and precipitation processes under aeronautical standards for approval. This work is part of a larger project, carried out in collaboration with several aeronautical companies, to compare and validate different metal additive manufacturing technologies: SLM and LMD-w.
The results will be used as a demonstrator to validate both technologies in the manufacturing environment of engine or propulsion parts and for both aeronautical and space applications.
UNS’s LMD-w technology can generate large axisymmetric geometries, up to 2 meters in diameter, increasing capacity in terms of part dimensions, where SLM technology is limited in size. It also offers advantages in deposition productivity and even in the characteristics of the generated part, with an absence of porosity or discontinuities. Furthermore, SLM allows the creation of more complex geometries.
The findings of this project will be presented to various R&D departments of large aeronautical manufacturers, where they will be able to streamline prototyping and functional testing, which until now has been limited by traditional preform casting and machining technology, where start-up costs are very high and lead times slow down development and validation work.
This project is co-funded by national and European R&D aid budgets.
