This presentation will share information on what to expect when using additive manufacturing technology to build, repair, and coat metal components. Topics will include a basic explanation of the directed energy deposition LENS technology and the materials capabilities of this technology. We will discuss the processing methods for oxygen sensitive materials such as Titanium, Tantalum, Waspaloy, and Aluminum; processing capabilities in non-inert atmosphere for Stainless Steels, Inconels, and Bronzes. Finally, we will focus on microstructural evolution after LENS processing and the effects of rapid cooling rates (103 to 105 K/s) on subsequent mechanical properties of the material. Discussions of examples will demonstrate the capabilities of the LENS technology as a tool for near net shaping, high value repair as well as a tool for materials innovation.
