摘　　要：基于FDM型的3D打印技术不仅让设计师的各种创意得以实现,更能够促进低碳保护,但其精度及表面质量无法满足艺术相关产品的外观需求。因此,设计一种基于全局搜索PID算法的FDM型3D打印温度控制方法。该方法选用无毒环保的PLA材料,并通过全局随机搜索策略对PID参数进行实时校正,实现对3D打印后处理装置中加热温度的控制,从而获得更好的产品表面成型效果。采用FPGA进行仿真控制测试,结果表明,相比于传统PID控制器,提出方法具有较好的鲁棒性和控制精度,兼顾了FDM型3D打印的美感性和环保性。The FDM-based 3D printing technology can realize the various creativity of designers,and promote the low-carbon protection,but its precision and surface quality can′t meet the appearance requirements of art-related products.Therefore,an FDM.type 3D printing temperature control method based on global search PID algorithm is designed.The method selects the non-toxic and environmental PLA material,and corrects the PID parameters in real time by means of global random search strategy,which can realize the control of the heating temperature in the 3D printing post.processing device,and obtain a better surface forming effect of the product.FPGA is used for simulation control and test.The results show that,in comparison with traditional PID control method,the proposed method has stronger robustness and higher control precision,and takes into account the aesthetic and environmental protection of FDM-type 3D printing.
