摘　　要：介绍了激光固化快速成型的工作原理。关键零件之一的工作台是工件最主要的支撑平台。从工作台的精度、强度、自由度约束、液面平整能力等五个方面进行了分析,首次提出了工作台的设计准则。在这个准则的指导下对工作台进行了结构设计、调平结构设计和自由度约束设计,也对工作台的材料选用和加工工艺进行了分析。在实际生产中的应用证明了工作台的设计准则和设计方案是可行的,为激光固化快速成型工作台的设计提供了理论依据,且具有较高的工程价值。The principle of Stereo Lithography Apparatus is introduced.The Workbench is one of the key components ,and it is the most important supportive platform of the workpiece.The design criterion of the workbench is put forward for the first time ,by analyzing five aspects of the precision,strength,restrict degree of freedom,the ability to smooth surface and so on.Based on the criterion,the workbench of struc- tural design,the balance structure design and the degree of freedom constraint design are devised,and the materials selection and machining technics of workbench is analyzed.The application of the workbench in the actual production shows that the design criterion and the design proposal is feasible, providing a theo- retical basis for design of the workbench for Stereo Lithography Apparatus ,and is suitable for engineering application.
