Abstract Scope |
In-situ monitoring during LPBF has garnered serious attention recently with some form of monitoring appearing on all commercially available machines at present. In this presentation a workflow will be described and implemented which leverages in-situ optical signals (namely pyrometry and photodiode) with ex-situ x-ray computed tomography (XCT). This workflow characterizes not only internal defects but also geometric conformance. This work will address common occurrences within the field relating to data management, exploratory analysis, processing, and relevant metrics. Finally, the workflow is implemented for quality assessment on lattice structures produced with LPBF with good results. Prepared by LLNL under Contract DE-AC52-07NA27344. |
