Additive manufacturing is typically a digital process where a digital model of a part is input into a 3D printing device to create a complete part. If the quality of the part is good or bad, the part needs to be judged by an off-line nondestructive detection mode such as industrial CT, ultrasonic flaw detection and the like or a destructive detection mode such as stretching, fatigue and the like, and once a problem occurs, the serious waste of manpower, material resources and time can be caused. The metal laser additive machining process is a very complex metallurgical process, and the repeatability and quality consistency of the machining process are difficult to ensure by the existing technical means. There is often a greater dispersion between different regions of a part, part-to-part, between different batches of the same equipment, and between the same parts produced by different equipment. This greatly restricts the wide application of laser additive manufacturing, especially the mass production of high value-added parts. Therefore, the traceability of the printing process of the metal 3D printing equipment parts is very necessary to be ensured.
