First Claim
1. A photocuring type 3D printer (4), comprising:
- a sink (41) for containing a forming liquid (40);
a glass layer (42) disposed on a bottom of the sink (41);
an adjusting unit (44) disposed on one side of the sink (41) and controlled to move horizontally;
a membrane (43) disposed above the glass layer (42), one side of the membrane (43) connected to the adjusting unit (44), the other side of the membrane (43) connected to the other side of the sink (41) opposite to the adjusting unit (44);
an emitting unit (46) disposed below the sink (41) and configured for emitting lights toward an internal side of the sink (41);
a forming platform (45) disposed above the sink (41); and
a microprocessor unit (47) electrically connected to the adjusting unit (44), the emitting unit (46) and the forming platform (45);
wherein, the microprocessor unit (47) is configured to control the adjusting unit (44) to execute homing for tightening the membrane (43) before starting to print a printing layer of a model (5), and the emitting unit (46) is configured to emit lights for solidifying the printing layer and attaching to the forming platform (45);
wherein the microprocessor unit (47) is configured to control the adjusting unit (44) to move for relaxing the membrane (43) after the printing layer is solidified, and is configured to control the forming platform (45) to move along a z axis for peeling the printing layer from the membrane (43).

Abstract
A photocuring type 3D printer (4) includes a sink (41) for containing a forming liquid (40), a glass layer (42) disposed on the sink (41), a membrane (43) disposed above the glass layer (42), an emitting unit (46) disposed below the sink (41), and a forming platform (45) arranged to immerse in the forming liquid (40) for constructing a model (5). The 3D printer (4) further includes an adjusting unit (44) disposed at one side of the sink (41). One end of the membrane (43) is connected to the adjusting unit (44), and another end of the membrane (43) is connected to the other side of the sink (41) opposite to the adjusting unit (44). The 3D printer (4) controls the adjusting unit (44) to execute homing for tightening the membrane (43) before solidifying the model (5) and controls the adjusting unit (44) to move for relaxing the membrane (43) after the model (5) is solidified, and controls the forming platform (45) to move after the membrane (43) is relaxed for peeling the model (5) from the membrane (43).
