Abstract
This study addresses the challenges of adding functionality and hybridizing processes in additive manufacturing. It focuses on embedding a gold-coated optical fiber into an INOX structure, aiming to extend this process to optical sensors like fiber Bragg grating arrays. The primary concern is the sensor's resistance to high temperatures during metal deposition, while the second challenge involves the adhesion of filler material to the sensor and structure. The feasibility is assessed through a finite element thermal model and mechanical testing, confirming the process's viability. Successful light transmission through the fiber and tensile tests indicate structural integrity and reduced ductility, warranting further investigation under varying load conditions.
