Special makeup companies are able to overcome the difficulties resulting from increase in labor costs by enhancing work efficiency through fabrication of prosthesis using 3D printing. With accurate fabrication being enabled, a given business area can be broadened to tailor-made prosthesis such as anaplastology. In this regard, the current study attempted to investigate the possibility of digital processing through special makeup molds and silicon patches designed using a FDM 3D printer, and the results are as follows: First, when a design modeled through the 3D graphics software 'ZBrush' was printed using a FDM 3D printer, the exact shape and surface texture which were observed on the computer monitor could be exactly obtained. Second, negative molds fabricated with flexible TPU filament were easier to use and displayed a more complete silicon mold than PLA filament-based negative molds. Third, the support, which is a disadvantage of the 3D printer, it was able to align objects or split the molds in such a way so that no support was formed in the slicing program. Fourth, the shrinkage rate of the outputs acquired through PLA or TPU filament did not change the shape of the silicon molds. Fifth, the texture of the fine contours which was found in silicon molds varied depending upon the object alignment angle in the slicing program. They can also be viewed differently depending upon the angle of lighting. To use a 3D printer in the fabrication of special makeup molds, therefore, it is necessary to examine how to fabricate them easily by concealing contours as much possible. It is also necessary to analyze the images acquired after attaching the colored silicon patches and check their availability.
