| Abstract Scope |
In-situ monitoring techniques are gaining importance for metallic additive manufacturing methods to reduce the time spent in subsequent quality control stages by using the data obtained from process monitoring. Although different systems based on thermal imaging or emission detection have been developed mainly for process monitoring, there is a need to better understand the relationship between the monitored data and the final part quality. Thus, this study focuses on correlating the melt pool monitoring (MPM) data to material attributes and further optimize laser-based powder bed fusion (PBF-LB) process parameters for a high strength Al alloy (Scalmalloy®). A systematic approach modifying the laser power, hatch distance, exposure time, and scan speed was used for process parameter optimization. The outcomes of the MPM were compared with optical density measurements and surface texture analysis. The findings highlight the efficacy of melt pool monitoring in guiding process optimization efforts for PBF-LB. |
