Abstract
Thermocouples and fiber-optic sensors were embedded in an SS316 matrix with LPBF AM. After laying the sensors in printed or machined channels, additional SS316 material was printed over the top, thereby embedding the sensors in the SS316 matrix. By optimizing processing parameters, the functional sensors were successfully embedded in the SS316 matrix with good bonding and minimal air gaps. Moreover, demonstrating well-embedded fiber optics showed that strain could be properly measured in the embedded region of the fiber. Future work will expand the use of embedded sensors in more relevant nuclear components for continuous, site-specific temperature and strain monitoring.
