In-situ acoustic signals correlation of process parameters in laser powder bed fusion

• Laser powder bed fusion (LPBF) is a metal additive manufacturing technique in which repeatability is a major concern in quality results.
•          An optical microphone was used to monitor the acoustic emission during the LPBF process.
•          The analysis showed a strong correlation between the acoustic signals and the process parameters.
•         This methodology allows for the evaluation of process flaws and overall quality.
