In this report, a method for restoring existing plaster reliefs using a 3D scanner and 3D printer was proposed. In Chapter 2, the material properties of gypsum such as strength, surface hardness and fluidity were investigated experimentally. Chapter 3 reports the results of trial restoration of gypsum relief installed in the trial interior by using a 3D scanner and 3D printer, and in Chapter 4 the process for restoring existing gypsum reliefs using a 3D scanner and 3D printer was proposed.
