- 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.
