Directed energy deposition (DED) is an additive manufacturing technique that uses laser power to melt the depositing metal powder into the melt pool on the substrate and form a layer. Process variables of DED have a significant influence on the mechanical characteristics, and porosity is the major challenge to DED parts. Therefore, it is essential to comprehend the factors controlling porosity. This work uses DED to produce high-density Inconel 718 using process parameters. It aims to produce low porosity in the parts. A thorough microstructural analysis was done to determine surface porosity. Single-track deposits with porosity less than 0.23% were discovered to be produced under conditions of high energy input and low scan speed. Seven circumstances with an aspect ratio larger or equal to three and a track dilution ranging from 30 to 50% were identified.
