Abstract: Additive manufacturing (AM) has expanded significantly in recent decades as a result of considerable advancements in laser technology and metal powder fabrication. It enables the quick production of near-net-shape designed parts from a digital CAD file without the need of dies or moulding. Nevertheless, one of the major challenges in Laser-Powder Bed Fusion (L-PBF), for example, is the disparity in the characteristics of the manufactured parts. The fundamental reason for this is the non-stationary character of the melt-pool area, which is accompanied by weld fumes, metal evaporation, plasma, and spark production. These effects become more pronounced within the individual printer as the amount of fumes suspended and circulating with the inert gas increases over time. Furthermore, depending on the build chamber size and gas flow design, these effects vary from printer to printer. This article is focused on investigating the (L-PBF) process in a step-by-step basis and presenting it to researchers, technologists, and even manufacturers, particularly those who are new to or have little knowledge of this technology. The study focuses on the key difficulties that must be studied and learned in order to build a functional metal part in an Additive Manufacturing (AM) facility.
