Laser Metal Deposition (LMD) uses laser and powder to build coatings and 3D structures. This additive technique has many benefits, including low heat input, and a capability to get to very near, or net, shape. The size of components that can be created are not restricted in size in the way that other powder bed based approaches are. This lends LMD to large builds that could involve a hybrid, e.g. LMD onto forgings, style approach.

The Aerospace Sector, in response to increasing demand, is looking for manufacturing techniques that are cost effective, flexible and responsive. LMD can provide all of these because of, amongst other advantages, the high material usage rates involved and additive nature of the technique requiring no tooling. LMD can be used for prototyping and ‘fast make’ but is a viable production tool for production.

This presentation will give examples of 3D LMD build for industrial applications, including the creation of large net shape structures. As much detail as possible will be given as to the approach that has been taken in each instance, however, some detail is commercially sensitive.
