The primary objective of this paper is to investigate the laser wire 3D printing process stability using 316LSi steel. Deposition stability criteria were established based on the hypothesis that energy input and mass input are the sole determining factors. This study employed experimental analysis using a laser-wire 3d printing machine. The results indicate that there is minimum laser power value required to shape the first layer. It is also shown that lowering travel speed contributes to higher deposition stability. Moreover, the study shows that thermal stabilization is achieved within 2–3 layers. By implementing established in this study process parameters values, consistent layer height was maintained throughout the printing process of a thin wall.
