Laser directed energy deposition is an additive manufacturing process in which laser melted powder deposited at target spot. In the past few years, it has become more popular because it lets manufacturers make complex parts in small batches with a small number of post-processing steps. Fabrication of components in directed energy deposition takes lots of time. Therefore, it is necessary to study the build rate in laser directed energy deposition method. Optimum values of different powder feed rate, scan speed, and laser power on build rate are evaluated. It observed that the laser power is a significant process parameter in build rate followed by scan speed and powder feed rate for the printing of Inconel 718.
