Abstract: Focusing on additive manufacturing components, the current situation of the quality and reliability of additive manufacturing process was reviewed. The main factors affecting the quality of components were analyzed, the common failure modes of typical additive equipment and main testing standards and methods were sorted out, the existing problems of the reliability of the domestic additive manufacturing equipment were analyzed. And finally a quality reliability working system covering the design, manufacturing, acceptance and use of additive manufacturing equipment and its key functional components was constructed. Some references and suggestions are provided for the development of quality reliability of additive manufacturing equipment.
