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/OS Ⅱ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/OS Ⅱ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 μC/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 μC/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.
