Design of the Glue Conveying System for Powder-paved 3D Printer

For the powder-paved 3D printing technology, an effective conveying glue control system is proposed. Taking the speed control of piston that squeezes the glue as the core of this design, a set of hydraulic control system for glue conveying is designed. The test model of the glue conveying control system is established. The system is simulated based on the MATLAB/ Simulink module, and the PID controller is applied to improve the dynamic performance of the system. The simulation results show that this design of the glue conveying control system for powder-paved 3D printer has good stability, accuracy and rapidity under the premise of ensuring safety, and can meet the requirements of glue conveying.
