Numerical approach for the estimation of the deposited material on the laser material deposition process.

Abstract The Laser Material Deposition (LMD) is an additive manufacturing technique that has become one of the most noteworthy methods for coating and repairing components. It is also a key process in hybrid manufacturing systems that combine LMD and machining operations. One of the main difficulties of LMD is the large number of relevant parameters and the complex interdependencies that must be considered. Thus, process fitting is usually based on trial and error techniques. The present work proposes a series of developments based on the numerical modeling of the LMD process, with the aim of reducing the experimental tests to setup the process. [ABSTRACT FROM AUTHOR]
