Additive layer manufacturing processestechnology especially selective laser melting process has offered capabilities to produce samples with excellent mechanical properties. In this study, samples of 17-4 PH Stainless Steell open cellular structure with variousvolume porosity ranging between 60% and '90% has. been fabricated using direct metal laser sintering process. The mechanical properties were determined through uniaxial compression and hardness testing. The 60% volume porosily samplet showel the optimum compressive strength and modulus of elasticity compared to 70%, 80% and 90% volume porosity for [he compression test. For hardness test. the different Surfuce area seerns does not affect the hardness value of the samples
