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 ℃
