摘要
研究并联式3D打印机的结构设计。传统的3D打印机通过XYZ三轴导轨的运动,控制打印头将打印材料层叠起来形成空间模型;并联式3D打印机采用Delta并联机器人结构,由三根并联臂带动动平台,最终实现打印机喷头输出三个移动自由度。对并联式3D打印机的工作空间进行了理论建模,在adams下对其运动进行了仿真,对打印机的电气控制部分进行了设计。通过制造样机进行实验,验证了理论分析,并得出结论。并联式3D打印机具有更高的打印速度和精度,对零件的批量生产具有重要的意义。
Parallel3D printer has been studied.In the traditional3D printer,The print head is controlledby X,Y,Z triaxial rail movement.The printing material is squeezed out and stacked by the print head toForm the space model.Parallel3D printer adopts Delta parallel robot structure.The Moving platform iscontrolled by three parallel arms.The print head has three translational degrees of freedom.Theoreticalmodel for workspace of Parallel3D printer has been studied.The motion simulation has been done byadams.Electrical control has also been studied.By making the prototype experiment,conclusion is that:parallel3D printers possess higher printing speed and accuracy.It has important implications for massproduction of parts.
