Wire-arc based metal are additive manufacturing (mBAAM) is a potential disruptive manufacturing process for creating large-scale metal parts. Owing to its superior feature of high deposition rate and minimal material waste, mBAAM enables one to print a part up to approximately 10 feet tall. For this technology to be widely adopted for manufacturing critical structural component, a tight control of process is required. Under dynamic printing conditions and complex geometries, part deformation is primarily associated with varying thermal cycles influencing internal stress buildup. This can lead to unfavorable part deformation during printing. In this study, a large scale thermo-mechanical simulation using finite element method (FEM) has used to manage part distortion and deformation on curved-sheet geometry. The transient part deflection is tracked in the simulation and then compared to untracked case for in-depth understanding on the deformation mechanism. Ultimately, potential solutions will be suggested to avoid undesired part deformation.
