Abstract

The increased use of metal additive manufacturing in production components makes quality control essential. The performance of parts produced by laser powder bed fusion depends on optimal process-parameters and the careful selection of scanning and building strategies for complex parts. In-situ acoustic emission provides a suitable solution for directly monitoring the laser powder bed fusion process during manufacturing. This paper shows the effect of different melting modes on the sound pressure and frequency spectrum during the laser powder bed fusion process. The results present valuable information for online monitoring development.
