| Abstract Scope |
Implementing robust statistical process control will address many challenges that prevent widespread industrial adoption of Laser Powder Bed Fusion (LPBF) Metal Additive Manufacturing. Presently, vast amounts of heterogeneous data from multiple in-situ monitoring sensors capture process information in real-time across length and time scales. This work demonstrates an effective method to parse and analyze this data, extract valuable information, and apply multivariate statistics to develop control charts for monitoring the LPBF process. This will enable a direct approach to layer-wise monitoring of the build, to track and quantify process variations across builds on the same machine and also compare performance across machines. Post-build part characterization helps establish correlations between the part properties and process state measured in-situ. Appropriate process control measures and critical limits can then be implemented for each process variable (or any combination), commensurate with the tolerance in part property allowables depending on the end-use application. |
