| Abstract Scope |
Cold spray additive manufacturing (CSAM) is an emerging technology within AM, with unique advantages due to the low temperatures compared to fusion-based AM process, as well as high build rates. However, special challenges exist, especially in producing sharp corners and edges, as well as in controlling the thickness of the deposit layer by layer. To successfully build arbitrary 3D shapes using CSAM, toolpath planning is needed to ensure the desired part is fully within the envelope of the final deposit. In this work, a toolbox for pre-build planning is developed, from parameter selection to part slicing to layer-wise toolpath control, including prediction of the final as-built geometry. Toolbox performance is validated through experimental deposition and user feedback. The ability to iterate the build plan before deposition to optimize for key process outcomes saves time and money, and is a valuable step towards qualification of CSAM for applications in industry. |
