摘要

低温沉积成型是一种现代绿色的增材制造技术。在沉积过程中随着沉积层的增高,冷冻所需要时间也在变化。建立了低温沉积过程的温度场模型,运用数值模拟的方法对沉积过程的温度变化进行模拟仿真。分析出凝固时间和初始温度、沉积层数、环境温度和层间等待时间的关系,找到了最短冷冻时间,提高了沉积效率。低温实验的结果也证明了模型的正确性。

Abstract

Freeze fabrication process is a new modern green additive manufacturing technology. During the depositing process,the freezing time needed would change with the increase of the deposition layer. The paper established the temperature field model of deposition process and simulated the temperature change of deposition process using numerical simulation. The relationship of depositing time with initial temperature,the number of depositing layer,environment temperature during the ice part building process and waiting time between layer and layer was analyzed and the minimum waiting time was found with a better depositing efficiency. The experiment result is also agree with the model proposed.
