摘　　要：针对目前国内外选择性激光烧结打印机普遍采用PC工控机、运动控制卡或可编程逻辑控制器作为控制系统硬件平台,不仅操作复杂且价格昂贵等问题,设计一种基于ARM的激光烧结打印机控制系统。该系统以STM32控制器作为主控单元,丰富并完善相应的扩展电路以及人机交互界面等,可以实现对激光、温度以及电机运动进行控制。基于设计的控制系统搭建样机进行烧结实验,结果表明:该控制系统各模块运行稳定,加工件表面光滑、结构清晰,在满足基本工艺要求的同时大幅度降低了设备成本。At present,PC industrial control machines,motion control cards or programmable logic controllers are generally used as the control system hardware platform of selective laser sintering printers at home and abroad,which is not only complicated to operate,but also expensive.To address the problem,a laser sintering printer control system based on ARM was designed.In the designed system,STM32 controller was used as the main control unit,the corresponding expansion circuit and human-machine interface were enriched and improved,to achieve the control to the laser,temperature as well as the motor motion.Based on the designed control system,the prototype was built for sintering experiments.The results show that each module of the control system runs stably,and the processed parts have smooth surface and clear structure.In addition,the equipment cost is greatly reduced while meeting the basic process requirements.
