In order to improve the efficiency of charging and molding of the explosive network， as well as the energy performance， high-energy azide binder 3，3-diazide methyl oxetane-tetrahydrofuran copolymer （PBT）， ultraviolet （UV） curing acrylate and hexanitrohexaazaisowurtzitane （CL-20） were selected as bonding system and main explosive respectively， an ultraviolet assisted curing CL-20-based energetic ink was designed， and using a 3D printing device to write. Rheometer， scanning electron microscope （SEM）， X-ray diffractometer （XRD）， and shore durometer were employed to characterize and test the rheological properties， microstructure， crystal form and hardness of the molded composite. Results show that the ink system is stable when the content of CL-20 is 82%. The curing efficiency of ink is fast with UV assisting， and the surface of molded sample is smooth. The hardness is 70 HA. The special height of impact sensitivity of the composite is 20 cm higher than the raw material； the test of detonation performance shows that the detonation wave can transfer 90° corner， and the critical detonation size reaches 0.387 mm when the line width of charge is 1.2 mm.
