Abstract: Disclosed is a method for manufacturing a 3D printing structure, the method including: producing a molded body by performing 3D printing on paste including printing powder in a coagulation bath including a hydrogel; hardening the molded body produced in the coagulation bath; and removing the hydrogel in the coagulation bath. A method for manufacturing a 3D printing structure, which is provided according to an aspect of the disclosure, does not require printing of a separate support, and thus it is possible to save time and costs. A post-processing process for removing a support is not required. Thus, a process is further simplified, and there is no risk of damage to a structure.
