Abstract:
Disclosed are a photocuring 3D printing method and a photocuring 3D printing system. The photocuring 3D printing method comprises the following steps: moving a forming platform (2) downwards; extracting a cavity (12) provided between a release medium (6) and a light-transmitting member (7) to a first negative pressure state, and then performing exposure so as to perform photocuring processing on a printing material (10); and after exposure is completed, extracting the cavity (12) provided between the release medium (6) and the light-transmitting member (7) to a second negative pressure state, and moving the forming platform (2) upwards to conduct a stripping operation.
