摘要

本文基于帕尔贴制冷片研制出一种新型石墨烯材料3D打印快速冷冻成型平台，它具有低噪音、重量轻、高可靠性及结构紧凑等优点。利用该平台进行了初步实验并确定了控制策略，采用模糊-PID控制方法对快速冷冻成型平台温度进行控制实验研究。6组实验结果表明：该快速冷冻成型平台能使平台温度在-40~0 ℃之间连续可调，超调量在4.8％以内。-5、-10、-15、-20、-30、-40 ℃的超调量分别为4.8％、3.9％、3.3％、2.8％、2.2％、0，调节时间为88、94、106、124、76、92 s。在设定值附近几乎保持恒定，成型平台表面无温度梯度存在。石墨烯浆料成型精度高，满足石墨烯3D打印成型要求。

Abstract

In the study

a new novel graphene 3D printing rapid freeze forming platform was developed based on the Peltier device. It exhibits advantages including low noise

light weight

high reliability

and compact structure. Experiments were performed on a platform to determine the control strategy. The study on temperature control was conducted via the Fuzzy-PID control method．Six groups of the experimental results indicate that the quick frozen processing platform continuously adjust the temperature between 40 ℃ and 0 ℃

the overshoot volume is within 4.8%. -5
