摘要：

With extrusion deposition technology as the core, based on the features of high viscosity and no-resistant to high temperature for propellant, the extrusion deposition rapid prototyping system for propellant was designed and a complete prototype was built. Using a certain ZY propellant as raw material, different materials with concentrations of 27.3%, 33.3%, 38.5%, 42.9%, 46.7% and 50% were prepared. Through 3D printing extrusion experiments, it is found that there is a polynomial function relationship between the inner diameter of the needle and the material concentration. The filling speed range is 2-4 mm•s-1, the filling rate range is 70%-90%, and the temperature range of the bottom plate is 25-45 ℃. On this basis, the propellant 3D printer was used to print the propellant, and the compression test was carried out. The results showed that the compression strength of the propellant could reach up to 230 MPa. © 2021, Editorial Board of Chinese Journal of Energetic Materials. All right reserved.
