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.

Abstract: A method for producing granules of a uniform size includes preparing an organic member solution, uniformly dispersing an inorganic member in the organic member solution at a weight ratio of 1 to 10 based on an organic member to form an organic-inorganic composite solution, spraying the organic-inorganic composite solution in an electrostatic charge manner, and polymerizing the sprayed organic-inorganic composite solution to form a hydrogel phase. The granules having a uniform size may be mass-produced in a short time and may be produced at a high yield. The method may be applied to a variety of fields, such as a pharmaceutical field, a medical field, a cosmetics field, and a food field and may replace a conventional spray drying method.
