Abstract: Aiming at limited height of the Chocolate 3D printing when the temperature of natural environment is high, chocolate 3D printing modeling conditions was studied, the optimum modeling temperature of chocolate 3D printing is from 10 centigrade to 16 centigrade, and on this basis, from the view of thermodynamic simulation using fluent,3D printing modeling environment was constructed by adopting semiconductor refrigeration method, the relationship among multiple factors of the housing space and the power of semiconductor coolers that affect the modeling conditions, including the influence of ambient temperature on the modeling conditions were analyzed, and the design basis of chocolate 3D printer was reached. 3D printing comparative experiments of whether installing semiconductor coolers through certain housing space and at ambient temperature were conducted, which verifies the validity of the design. The results indicate that semiconductor refrigerator can greatly improve the chocolate 3D printing modeling conditions, as well as solve the problem of Chocolate 3D printing modeling height under the condition of natural environment.
