The invention belongs to the technical field of light-curing 3D printing, and in particular relates to a dynamic test system and a working method for the characteristics of a DLP type 3D printer polymerization inhibition zone. plate, to divide the annular flow channel into corresponding test areas; it also includes: several diaphragm placement components, gas input components, thickness data acquisition modules, forming base simulation components and driving components. The system and working method are provided with a test area, which can cooperate with the gas input component, the driving component, and the forming base simulation component to study the oxygen supply pressure, the movement speed of the forming base simulation component, the cross-sectional area of the forming base simulation component and the annular flow channel. The influence of the ratio of the cross-sectional area on the thickness of the polymerization inhibition zone is beneficial to the optimization of the printing process. |
