The isocyanate and the polyol are subjected to a polymerization reaction, and the hydroxy acid, the hydroxyl gadoleic acid ester and the monohydric alcohol are adopted to control the content of NCO in a system until the NCO value in the dispersing agent is less than 0.1. The dispersing agent obtained by the invention can directly replace a commercially available dispersing agent to disperse various organic or inorganic pigments and prepare various inks. The photo-curable 3D printing ink prepared by using the dispersing agent has excellent dispersing performance: the dispersing particle size is less than 5 microns, the viscosity is 10000-20000cps, and the viscosity variation is small; and the comprehensive performance is good: the gloss of a coating film can be greater than 95 at an angle of 60 degrees, the covering power is greater than 85%, and the pencil hardness is greater than HB.
