摘　　要：针对目前市场上多数增材制造设备成型加工时材料单一,成型件功能单一等缺点,课题组提出了一种低成本、基于数字化光处理技术(DLP)的多材料增材制造系统。在分析传统数字光处理技术工艺基础上,课题组设计了一种多材料线性切换装置和清理装置,并搭建相关的成型系统平台;采用Lab VIEW虚拟仪器平台作为控制系统核心,编写上位机程序,Arduino做下位机运动控制,建立从机电设计到多材料工艺过程一体化策略。课题组使用商业光敏树脂应用测试,结果表明系统能够实现层厚及成型件尺寸的精确控制和打印切换功能。系统能实现多材料加工成型,打印具有一定功能性的器件。In order to solve the problems of single material during processing and single function of machined parts of the additive manufacturing equipment on the market,a low-cost multi-material additive manufacturing system was designed based on digital light processing( DLP) technology. Analyzed the process of traditional DLP technology,designed multimaterial linear switching device and cleaning device,and the multi-material platform was then accordingly developed.The LabVIEW virtual instrument platform was used as the core of the control system,and the upper computer program was written,the Arduino was used for the lower computer motion control,the integrated strategy from the mechanical and electrical design to the multi-material process. The results by commercial photosensitive resinverify that the system has precise control of layer thickness and x/y size and print switching capabilities. This system can realize multi-material processingand print devices with certain functions.
