Analysis of mechanical properties of 3D printed metallic specimens of aluminum (CL31) bronze (CL80) material manufactured at varying laser scanning speed

Abstract In our research work, we analyzed the mechanical properties of 3D-printed metallic specimens aluminium bronze material. evaluation, had five groups specimens, manufactured at different laser scanning speeds. total, 25 for which examined various parameters like ultimate tensile strength, engineering yield point, relative strain, and hardness. Results showed that prepared with a lower speed 300mm/s lowest strength. The strength increased increasing scan highest was attained by fourth group were produced 500mm/s. strain also laser. Brinell hardness test an elevation in values
