Abstract Real-time monitoring of the temperature field distribution of the electron beam fuse additive manufacturing process is of great significance for suppressing deformation and improving the manufacturing quality of electron beam fuse addition. A set of dynamic temperature measurement array system for electron beam fuse additive manufacturing process was developed. The system design, hardware integration, software preparation and test verification were carried out for the whole device. The results show that the follow-up temperature measurement array system can work stably in the harsh environment of high vacuum, high temperature, high radiation and high metal vapor in the process of electron beam fuse addition manufacturing, and can not only measure temperature under normal conditions, but also the temperature can be continuously measured when the additive substrate is heated and deformed, and the functions such as dynamic temperature measurement and real-time display, storage and reconstruction analysis of the temperature field can be realized, and the display image is intuitive, the system stability is strong, and the operation is simple.
