摘要:
气动挤料方式作为挤出式生物3D打印机常用供料方法,存在气动挤料与打印头移动协调性差,打印效果不理想等问题,我们为此提出气动挤料与打印头移动协同控制方法,实现打印模型中纤维线条直径一致性控制. 文章介绍了气动挤出系统组成和电控系统组成,建立了气动挤出过程数学模型,并通过AMESim-Matlab联合仿真得到打印头气动挤料速度与打印头内外压差、针头内径的关系,以及气动挤料系统工作时打印头移动目标速度. 最后提出了气动挤料及打印头移动速度协同控制方法,通过打印实验验证了协同控制方法的有效性.
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.
