摘　　要：文章将DLP光固化成型技术与熔模铸造工艺相结合,研制了适用于陶瓷浆料打印的光固化增材制造装备。以实现DLP光固化成型工艺参数:曝光时间、曝光层厚及曝光强度等为设计出发点,合理设计光固化打印机的选型及零部件布置,验证最佳工艺参数,确定了设备最佳曝光时间为30~35 s;最佳打印曝光层厚为0.1 mm。By integrating DLP light-curing technology with the investment casting process,a synergistic approach harnessing the strengths of both methods becomes achievable.A specialized light-curing apparatus,tailored for ceramic paste printing,has been engineered.The development process prioritized the configuration of essential DLP light-curing parameters:exposure time,exposure layer thickness,and exposure intensity.This involved meticulous selection of suitable light-curing printers and the strategic arrangement of components.Extensive design considerations culminated in the validation of optimal process parameters.Consequently,the equipment's optimal exposure time has been definitively established at 30-35 s,while the most effective printing exposure layer thickness stands at 0.1 mmm.
