Embodiments of the systems and methods disclosed herein can related to an additive manufacturing process involving the use of an algorithm to determine the optimal build orientation of a build that will result in minimal thermal distortion during the build. The algorithm includes a momentum of inertia based objective function, wherein the output of the objective function can be used as a proxy for thermal distortion. In some embodiments, objective function can be configured as a mathematical matrix with mathematical variables modeling rotation angles of a build. The rotation angles can be in the x-, y-, and/or z-geometric planes of the build with respect to the build plate. An objective function output can be calculated for each iterative rotation. The minimum objective function output can be used as the rotation representing the orientation that would result in minimal thermal distortion.
