摘要：
The application of 3D printing technology in the performance regulation and control of aluminum-based energetic materials were exposited. The effects of 3D printing ink optimization and microstructure optimization on the burning rate and mechanical properties of molding materials were discussed. It is found that the addition of fluoropolymer or detachable polymer in the ink can significantly affect the initial reaction path of aluminum powder and adjust its ignition and combustion characteristics. As a binder in the application of energetic materials, it can rapidly release a large amount of gas products and inhibit the agglomeration of aluminum powder, which is a new path for future binder selection. The microstructure optimization of 3D printing energetic materials mainly utilizes methods such as changing the spatial structure, distribution gradient, and specific structure of components to improve the combustion efficiency of energetic materials. According to the current achievements and development trends, the combination of ink and microstructure optimization will be a potential direction for the manufacture process of energetic materials in the future.
