| 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, -10, -15, -20, -30, -40 ℃is 4.8%, 3.9%, 3.3%, 2.8%, 2.2% and 0, respectively, and the adjusting time corresponds to 88, 94, 106, 124, 76, and 92 s. The setting temperature near the set value is almost constant. A temperature gradient is absent on the surface of the forming platform. Graphene ink forming with high accuracy satisfies graphene 3D printing requirements. |
