| Abstract Scope |
The lack of reproducibility of parts manufactured via Laser Powder Bed Fusion (LPBF)across platforms negates on-demand production of moderate- to high-criticalitycomponents. While all LPBF systems share core sub-systems governing process physics,the practical implementation and characterization of gas flow, scanner control, lasercaustics, feedstock spreading, and atmosphere regulation are often opaque to the user,undermining confidence in traceable outcomes and preventing reproducibility. We identifythree key barriers to achieving make/model-agnostic reproducibility. First, the industrylacks a common build file format analogous to CNC g-code, preventing quantitativeinspection of process intent. Second, no standardized approach exists for defining amachine configuration profile to enable a digital twin representation of processingattributes. Third, there is no universal machine execution log to capture actual versusplanned trajectories, laser state, and chamber conditions. Here, we demonstrate anexample implementation addressing these three foundational pillars. |
