Research on Temperature Control System of Desktop 3D Printer Based on Fuzzy Adaptive

In the printing process of desktop 3D printer, the printing consumables is to be heated and melted, and the layers of the extrusion layer are stacked. The heating temperature control system has the characteristics of nonlinearity, large inertia and large hysteresis, which it is some disadvantages for making the heating process take more time and inaccurating temperature control. Aiming at the above problems, a fuzzy adaptive desktop 3D printer temperature control strategy is proposed in this paper. The ARM LPC1768 high-performance microcontroller is combined with the fuzzy adaptive feature to implement temperature control fastly and precisly, and the temperature simulation model of the control system is established by Matlab/Simulink. The experimental results show that the fuzzy adaptive PID controller has the advantages of small overshoot, good temperature tracking performance, fast dynamic response and high reliability compared with the conventional PID control method. It is optimal for the temperature control of the desktop 3D printer.
