Abstract

Three-dimensional (3D) printing technology is a new and widely use technology in the manufacturing industry. However, the domestic manufacturing industry is underutilized due to various manufacturing flaws and surface quality problems. This study intended to derive ways to improve the surface quality of products by improving the surface roughness of the sand mold manufactured by 3D printing. The test results confirmed improved viscosity control of the mold wash coated on the surface of the sand mold. In conclusion, it was possible to derive that the mold wash had a direct effect on the sand mold surface and to improve surface quality through coating methods on the mold and core.
