针对自然环境温度较高时巧克力3D打印模型高度受限的问题,研究了满足巧克力3D打印的成型条件,在10℃~16℃之间为巧克力3D打印的最佳成型温度,以此为依据,利用fluent从热力学仿真角度,采用半导体制冷方法构建了3D打印成型环境,分析了影响成型条件的箱体空间、半导体制冷器功率多因素间的相互关系及外界温度对成型条件的影响,得出了巧克力3D打印机的设计依据。通过一定箱体空间及外界温度下是否安装半导体制冷器的巧克力3D打印对比实验,验证了设计的正确性。研究结果表明,半导体制冷能很好地改善巧克力3D打印成型环境,可以解决自然环境下巧克力3D打印的成型高度问题。

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.
