AB This research focuses on analysing the 18Ni300 maraging steel produced through laserpowder bed fusion. Specifically, it aims to examine the phase components using X-ray diffraction, themicrostructure through scanning electron microscopy, and the hardness of the different structurespresent in the manufactured material. The primary goal is to meticulously analyse the material andits microstructures. By doing so, a correlation between the hardness and each structure type, be itcellular or columnar, can be established. This will allow us to pinpoint any defects in the materialbefore any surface chemical treatment is carried out and facilitate a thorough examination of itsmicrostructure. A consistent pattern emerges across the samples through systematic measurementof microhardness distribution in various locations and detailed examination of the structure. Thefindings of the study reveal that the hardness of cellular and columnar structures exhibits a significantvariation based on the location of the measurement about cell boundaries. The hardness value isnotably higher in the combination of cellular and multiple layers, as the data indicat
