It is found that the functional parts of Al-Si-Mg aluminum alloys manufactured by selective laser melting (SLM) process have great interests in the automobile and aerospace industries. In engineering applications, characterization of the material deformation behavior is extremely important. In this work, we applied a statistical method for characterizing material deformation behavior on ASTM A370 standard Charpy V-notched samples built by SLM process. The samples were tested by ASTM E23 standard Charpy impact tester and the samples had five different building layer orientations: 0⁰, 30⁰, 45⁰, 60⁰, and 90⁰. We used a digital microscope for developing the 3d surface structure of the tested specimens. At a magnification of 300x, the microscope developed 3d surface morphology by depth-from-defocus (DFD) optical technique. We extracted a big volume of surface raw data from the 3d surface morphological image. We applied a probability density function for determining the crack propagation path of each sample.
