The goal of this work is to predict the effect of part geometry and process parameters on the direction and magnitude of heat flow heat flux in parts made using metal additive manufacturing (AM) processes. As a step towards this goal, the objective of this paper is to develop and apply the mathematical concept of heat diffusion over graphs to approximate the heat flux in metal AM parts as a function of their geometry. This objective is consequential to overcome the poor process consistency and part quality in AM. Currently, part build failure rates in metal AM often exceed 20%, …

With the rapid advancement of additive manufacturing technologies in recent years on both the microscale and the macroscale, research must be done to test the limits of currently available technologies. On the microscale, halloysite nanotubes have proven to be a viable platform for reinforcement of polymers and time release of loaded chemicals, as well as a substrate material for the deposition of nanoparticles. The range of materials are limited due to polarity conflicts, and often lead to wet chemical processes that use more toxic alternatives. Three-dimensional (3D) printing and macroscale additive manufacturing techniques can be used to generate custom structures, …
