A fundamental challenge in near-net shape materials processes is decoupling the resultant material properties from the shaping process itself. In conventional manufacturing, the fundamental materials properties are measured from a previously processed billet, which is later subtractively machined into its final shape. The thermal character and energy input that is used for a near-net shape process, on the other hand, play a role not only in defining the final geometric form of a finished build, but also in the fundamental materials properties that result from cooling rates and cyclic heat treatments during the process. I will discuss ongoing work to develop multiphysics modeling tools that predict shape, residual stress, and yield stress in additively built parts. These models are validated by thermal data recorded from on-board diagnostic cameras. The end goal is design and optimization tools for AM processes that aid in the qualification of high consequence parts.
