| Abstract: |
| In order to study the feasibility of the application of 3D printing manufacturing technology on solid rocket motor （SRM）， a typical milling to manufacture difficult-to-process metal support components for SRM was studied. The preparation techniques， basic performance， efficiency comparison， structure weight -lightening， use performance and other aspects were studied. The performance data， numerical analysis results and engineering application research path of a TC4 component manufactured by 3D printing were obtained. Compared with the traditional milling manufacturing process， 3D printed components can not only meet the requirements of engineering applications， but also cooperate with structural optimization design， achieving a 50% increase in manufacturing efficiency， a maximum weight reduction of 13.6% and a maximum tension of 63.9kN for lightweight structures. It provides a new way for the lightweight and efficient molding of difficult and complex parts to process， which is worthy of further in-depth systematic research. |
