围绕均质陶瓷材料和结构单一性能的应用范围受限问题,针对多材料陶瓷增材制造工艺,从整机、工作台、多轴运动模块、激光与振镜模块、喷射模块、传感与阀类模块和工艺模块等多态模块工作机理与集成角度出发,提出了立体光固化/喷射沉积复合工艺的增材制造技术,搭建了立体光固化/喷射沉积多材料陶瓷增材连续成形装备样机,研究了“涂+固+喷+固”的多系统协同运动工序,优化了多模块运动稳定性;分析了多工序复合工艺的组合逻辑,提出了系统集成方案,开发了多材料CeraMulti Slicer切片软件和复合工艺打印CeraMulti Driver组态软件,构建了光固化成形运动机构与喷射沉积模块协同运动机制及高精度集成控制系统,实现了切片和多矢量打印运动协同控制。结果表明:该技术可制备精度高、界面结合良好、无缺陷的多材料陶瓷样件。
In order to solve the problem that the single performance of homogeneous ceramic materials and structures limits their application,an additive manufacturing technology for the photocuring/spray deposition composite process is proposed from the perspective of the working mechanism and integration of polymorphic modules,including the whole machine,worktable,multi-axis motion module,laser and mirror module,spray module,sensing and valve module,and process module.A prototype of photocuring/spray deposition multi-material ceramic additive continuous forming equipment is built,and the multi-system collaborative motion process of“coating+solidification+spray+solidification”is studied to optimize the stability of multi-module motion.The combination logic of the multi-process composite technology is studied,and the multi-material CeraMulti Slicer software and CeraMulti Driver configuration software are developed.A collaborative motion mechanism and a high-precision integrated control system are developed for the photopolymerization forming motion mechanism and spray deposition module.The integrated preparation of forming control for multi-material ceramic parts is explored.The results indicate that this technology can prepare multimaterial ceramic samples with high accuracy,good interface bonding,and no defects.
