Abstract. This study investigates the mechanical properties of copper and aluminum samples produced through powder metallurgy using furnace sintering and laser sintering. The objective is to compare the properties of these samples with those of cast materials and evaluate the effects of varying process parameters on their properties. The samples were tested for punching force determination to evaluate their penetration strength. The results show that copper samples produced through furnace sintering with a 20-minute hold time have properties closest to cast copper and aluminum furnace sintering with a 30- minute hold time produces samples with the highest punching force and deformation value, while laser sintering for both metals is better suited for applications where strength is a more important factor than ductility. The comparison of fracture growth and ductile behavior among different samples produced through cast material, furnace sintering, and laser sintering processes revealed a reduction in deformation from cast materials to furnace sintered materials and a further reduction in laser-sintered samples. The findings of this study can assist in the development of materials with improved mechanical properties for specific applications such as filters, which require porous parts that do not necessarily require the same level of strength as cast materials.
