Proposed is a lacquer for treating a 3D printing-created printed matter that is configured to contain a perfluorinated acrylic resin having a relatively high surface hardness and excellent water resistance and contamination resistance, as well as an excellent force of adhesion to a printing resin making up a 3D printed matter. While the 3D printed matter that is printed through a photocuring-type 3D printer is cleaned and rinsed, an uncured resin remaining on the 3D printed matter is removed, and at the same time, a protective film layer is formed on a surface of the 3D printed matter by being coated thereon. As a result, the surface of the 3D printed matter is protected from damage during a post curing process. Furthermore, the 3D printed matter, which is to be manufactured, is also effectively safeguarded against quality degradation that is caused by contamination through the surface thereof and subsequent discoloration.
