s4: after the liquid level is stable, the height of the lifting platform (6) is adjusted to enable the cooling liquid to submerge the bottom of the substrate (10) without contacting the top of the substrate (10);
s5: the water pump (2) is turned on, cooling liquid is continuously pumped from the processing tank (1) into the liquid storage tank (3), and cooling liquid circulation is formed through the pipeline (7);
s6: adjusting the laser head (5) to be positioned at the original position of additive manufacturing, performing printing operation, in the printing process, waiting for 10-20s to cool and shape a printed part of the part in air, controlling the lifting platform (6) to descend until the printed part is immersed into cooling liquid, and performing next-layer printing of the part;
s7: repeating the step S6 to print until all the molded parts are immersed in the cooling liquid;
s8: cutting off a pipeline (7) without a water pump (2) between the processing tank (1) and the liquid storage tank (3), pumping cooling liquid of the processing tank (1) to the liquid storage tank (3) through the water pump (2), and then taking down the substrate (10) and printed parts.
