The present invention is intended to provide a cleaning apparatus for a 3-dimensional (3D) printing structure and a cleaning method for a 3D printing structure. To this end, the present invention provides a cleaning apparatus for a 3D printing structure, the cleaning apparatus including a hygroscopic paper supply part supplying a hygroscopic paper while the wound film-type hygroscopic paper is unwound, a hygroscopic paper collecting part winding and collecting the film-type hygroscopic paper, a film-type hygroscopic paper moving in a direction from the supply part to the collecting part between the supply part and the collecting part according to a mutual operation of the supply part and the collecting part, and a support part disposed on an opposite surface of a hygroscopic paper surface, on which the 3D printing structure is disposed, with respect to the film-type hygroscopic paper, and a cleaning method for a 3D printing structure, and a cleaning method for a 3D printing structure. According to the present invention, the 3D printing apparatus may be cleaned by using a minimum amount of solvent, and the mixture between materials may be prevented to remarkably improve the quality and integrity of the 3D printing structure.

Cleaning apparatus for 3D printing structure and cleaning method for 3D printing structure using the same

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.
