Selective Laser Melting (SLM) facilitates the integration of additional functionalities such as sensors into metallic parts. Such sensors can for example be embedded in sections of the parts that will no longer be accessible after manufacturing. Additionally they can be positioned close to the region of interest. Depending on the type of sensor it is even possible to monitor the structural health of the part itself. This paper discusses the integration of fibre optical sensors into SLM manufactured coupons in a commercial, industry scale, SLM machine. Such systems have limited accessibility for fibre handling but it lifts the embedding of sensors from lab environment to production facilities. The embedment procedure as well as the corresponding bonding quality is explained in detail. Measurement results and limitations related to the use of commercial SLM systems are presented, and the need for further research is pointed out
