Functionally graded porous materials (FgPM) are those in which porosity changes by the direction. FgPMs are created to solve the problems of optimal material mixing in alloys and delimitation in composite materials. Due to their sophisticated structure, functionally graded porosity material will be challenging to fabricate. In this research work, designing and development of FgPM using selective laser melting (SLM) and AlSi10Mg alloy. The novelty of the work was that component fabricated via SLM technique was graded along a linear direction to determine the effect of directional porosity. Initially, the material was analyzed by physicochemical analysis like energy dispersive spectroscopy (EDX), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Latter, SLM printed FgPM structure was analyzed using mechanical characterization in both heat-treated and as-built components. The results concluded that the hardness of the heat-treated sample has been reduced by solution treatment quenching and artificial aging. However, the value of compression strength was 9236 kg/m2 and hardness was 139 ± 5.64 HV for as-printed parts. The X-ray tomography was utilized for examination of the fabricated pores which confirmed that the linear direction grading was successfully done with structure pores.
