SYSTEMS FOR QUALITY MONITORING OF ADDITIVE MANUFACTURING USING ACOUSTIC EMISSION

A system (100) for quality monitoring of additive manufacturing includes an acoustic emission (AE) sensor (101) configured to be attached to an additive manufacturing substrate (103) and to output a sensor signal indicative of acoustic vibrations received at the AE sensor (101) and an AE module (105...

Beschreibung
Zusammenfassung:	A system (100) for quality monitoring of additive manufacturing includes an acoustic emission (AE) sensor (101) configured to be attached to an additive manufacturing substrate (103) and to output a sensor signal indicative of acoustic vibrations received at the AE sensor (101) and an AE module (105). The AE module (105) is configured to receive the sensor signal from the AE sensor (101) and process the sensor signal to determine at least one characteristic of an additive manufacturing process and/or an additively manufactured article.
