As a novel rapid prototyping sand casting method, 3D-printing is capable of producing any complex mould, which makes further structure optimization of the sand mould possible. Because of the connection between the production speed of 3D-printing and the structure of mould, it is necessary to optimize structure of 3D printed sand mould. In this situation, an optimum design method of the 3D printed sand mould is established, and the design process is introduced. Based on the mechanical property requirements, the thickness of the sand mould is taken as the optimization parameter, and the optimum design model is established. In the end, the optimum design of the casting sample is completed. Results show that the volume of the sand mould is reduced by 42.6% after optimum structure design, thus the efficiency of production is raised, and the cost of the resin-bonded sand is reduced.
