With the popularization of 3-D (three-dimensional) printed metals, the necessity for a method to detect internal flaws is increasing. We experimented with a 2-D (two-dimensional) graphite model of 3-D printed metal and measured the potential at various points throughout the model in a grid-like fashion. To simulate imperceptible flaws, we erased internal portions of the graphite and re-measured the potentials at the same points. Graphing our measurements, we created representations of nonlinear potential differences, allowing us to conclude that calculating potential in intervals over a conducting surface is a valid method to detect imperfections hidden within 3-D printed conducting surfaces under certain conditions.
