The invention relates to photocuring resin for fast forming and a preparation method thereof. The resin is prepared from the following ingredients in percentage by mass: 10 to 55 weight percent of cationic photocuring resin prepolymers, 10 to 40 weight percent of free radical photocuring resin prepolymers, 5 to 30 weight percent of cationic photocuring resin active diluents, 5 to 30 weight percentof free radical photocuring resin active diluents, 1 to 6 weight percent of cationic photoinitiator and 1 to 8 weight percent of free radical photoinitiator. According to the preparation method, eachraw material prepolymer and the photoinitiator are uniformly mixed according to a certain mass ratio at first; heating is performed for 30 to 80 min to obtain pale yellow transparent liquid; then, diluting agents are added for uniform mixing; the photocuring resin is finally obtained. By using the formula and the preparation method provided by the invention, the required product with high curingspeed, high dimension precision and high mechanical property can be prepared.
