Abstract:
Pneumatic extrusion is a common method for extruded biological 3D printers,but pneumatic extrusion and printing head movement is not well coordinated,thus results in the printing effect is not ideal. The collaborative control method of pneumatic extrusion and print head movement is proposed to realize the uniform control of fiber diameter in the printing model. The composition of pneumatic extrusion system and electronic control system are introduced,and the mathematical model of pneumatic extrusion process is established. Through AMESim-Matlab simulation,the relationship among pneumatic extrusion speed,differential pressure and inside diameter of the needle,and the moving target speed of the printing head during the operation of pneumatic extrusion system are obtained. Finally,The collaborative control method of pneumatic extrusion and printing head movement is proposed,and the effectiveness of the method is verified by printing experiments.
