when the printer is used, the first pneumatic sliding block (42) can drive the first sliding sleeve (52) to move through the first connecting rod (56) when moving, the second pneumatic sliding block (44) can drive the second sliding sleeve (54) to move through the second connecting rod (57) when moving, the whole second printing head (55) and the first printing head (45) move in the same action mode, therefore, the efficiency of three printing operations is high at the same time, the fan (14) is turned on, the gas printed inside can be collected through the fan (14), and the gas is purified and discharged through the activated carbon filter screen (12) and the nanometer optical touch coal plate (13);
after printing is finished, the movable plate (16) can be pulled, the outer protective shell (63) is pushed by hand, the motor (65) is opened, the saw blade (62) is driven by the motor (65) to rotate, the printed model is cut by the moving saw blade, the model is separated from the supporting plate (23), resin on the surface is scraped by the scraper (64), the supporting plate (23) is cleaned, if the supporting plate (23) and the model are required to be integrally taken out, the inserting rod (21) is moved, the inserting rod (21) is taken out from the clamping groove (221), and then the supporting plate (23) is popped out under the action of the spring (24), so that the supporting plate (23) can be taken out;
after the DLP photocuring 3D printing system is printed, the printed model is cut and separated by the aid of the hand-pushed saw blade (62) rotating at a high speed, so that the model is quickly separated from the supporting plate (23), the saw blade (62) can be cleaned through the sponge block (61), resin stuck to the surface of the supporting plate (23) can be scraped by the scraper (64), and the supporting plate (23) can be detached; the printing mechanism moves, and both sides of the sliding block are connected with another sliding sleeve through the connecting rod to drive the second printing head (55) to move, so that the three models can be printed simultaneously; and (3) filtering the gas generated by printing through the activated carbon filter screen (12) and the nanometer light-touch coal plate (13) by using a fan (14) and then discharging.
