Part Smoothing Models for Additive Manufactured Titanium

Additive Manufacturing (AM) is quickly transforming industrial manufacturing with the ability to produce high strength, low weight parts with intricate designs that are too complex to manufacture by conventional methods. However, the finishing/smoothing (post processing) of parts remains one of the biggest challenges for enabling full and affordable implementation of AM. This student team sought to create a model that accounts for reaction kinetics, gas, and fluid flow and how it interacts with intricate part shape to design an optimal chemical processing configuration on internal surfaces. This student team worked to include documentation on how the model was created, with attention to the underlying assumptions that were made and known limitations, as well as a copy of the final model (to include examples of how it is used, if built using common software).
