Printing substrate with sliding fulcrums at two ends of SLA photocuring 3D printer

The utility model discloses a two-end sliding fulcrum printing substrate of an SLA photocuring 3D printer. The two-end sliding fulcrum printing substrate comprises a printing substrate body, a bracketand two sets of guide plates. Each group of guide plates comprises an outer guide plate and an inner guide plate; at least two guide rod sliding blocks are arranged between the inner guide plate andthe outer guide plate. Linear guide rails matched with the guide rod sliding blocks are installed on the inner side of the outer guide plate in parallel. One end of the guide rod sliding block is fixedly mounted on the inner guide plate; the upper part of the guide rod slider is slidably fixed on the linear guide rail through a linear bearing; the inner guide plate is fixed on the bracket throughan adapter plate, and the printing substrate is borne above the bracket; and the two outer guide plates are fixed on a guide rail base of the printer. 本实用新型公开了一种SLA光固化3D打印机两端滑动支点打印基板，包括打印基板、托架和两组导板；每组导板均包括一块外导板和一块内导板；内导板和外导板之间设
