Integration of sensors during laser powder bed fusion

Abstract

Laser powder bed fusion (PBF-LB/M) is an additive manufacturing (AM) process to produce high-strength, functionally integrated, lightweight metal components which cannot be built conventionally. This article addresses the expansion of functionality by integrating sensors within closed cavities. For this reason, the building process was stopped just before the cavities were closed. After positioning the sensors, the building process was continued and a solid connection to the AM component was established.
