In the investigation, the primary process parameters of metal additive manufacturing (MAM) that affect the melt pool were examined to allow for a thermocouple embedment such that the sensor is capable of measuring temperatures within a standard operating temperature range for next generation heat exchangers, while maintaining an acceptable error listed by the manufacturer. Developing a melt pool capable of properly embedding a thermocouple is not only important for accurate temperature measurements but is critical in ensuring that standards for MAM parts are met, such as standards for 316L stainless steel powder. While the core of the investigation was to embed a thermocouple and confirm that the embedded sensor yields the same value for a nominal temperature as a sensor that is attached through traditional manufacturing processes, the part surrounding the embedded thermocouple must abide by industry standards so that it can be used in desired engineering applications.
