摘　　要：简要介绍了三维打印机原理与控制系统,重点论述了采用μC/OSⅡ操作系统开发三维打印机中任务的划分及任务间的通信技术。将三维打印分为4个用户任务,分别是触摸屏操作任务,显示屏显示任务,数据生成任务,打印任务。凭借μC/OSⅡ灵活的任务间通信的能力,采用消息邮箱Mbox从数据生成任务中将打印数据传送给打印任务。在不同任务中,将暂时不需要工作的任务挂起,而将需要工作的任务恢复运行,圆满地实现了三维打印的快速、精确控制。The principle and control system of 3D printer is introduced. The tasks division and intercommunication technolo- gy of the 3D printer based on t^C/OS II is mainly discussed. The 3D printing was divided into four tasks： touchscreen operation task, LCD display task, data generate task and print out task. Rely on the agile tasks intercommunicate ability of I^C/OS II, the print data was sent from data generation task to print task by Mbox. In different tasks, the needed task is resumed and the un- needed tasks are hung up. In this way, the fast and accuracy control of 3D print is realized.
