In order to maintain parts critical to using 3D printing technology, it is necessary to provide the user with information about powders, equipment, processing conditions, and inspection methods, as well as 3D CAD models used as input files for 3D printing operations. In order to address this issue, this paper proposes a manufacturing condition retrieval system that provides the information necessary for the maintenance of parts important to using 3D printing technology. To accomplish this, we define a data structure that stores manufacturing condition information for 3D printers. Then, after analyzing the user"s requirements, we design the manufacturing condition retrieval system. Finally, we implement a prototype system, construct a database using sample manufacturing condition sheets, and perform data retrieval experiments.
