This technology is mainly used in aeronautics to repair complex and expensive parts instead of replacing them. That way, the manufacturer saves a spare part and the cost of disassembly and reassembly. This is particularly useful for some expensive components. Instead of getting a new expensive metal part, it is now possible to fix it using DMD.
This laser metal deposition technology can also be used to repair existing parts. Indeed, Direct Metal Deposition is the only existing method we know, able to repair, reconfigure or resurface existing parts, molds, or dies by adding metal that matches the parent tool. This technique appears to be an excellent benefit for tooling processes. This singular 3D printing technique is also used for efficient coating and welding. It is possible to use it to reinforce components locally or to adapt them in terms of geometry
