The primary goal of cultural heritage restoration is to preserve historical and cultural legacies. Addressing object deterioration and restoring the original shape is crucial, especially for three-dimensional objects, as missing parts can affect the viewer’s perception. This study aims to address the challenges of appearance simulation and cost reduction in traditional restoration processes. Restoring missing parts traditionally involves sculpting or casting, which depends on the skill of the restorer and carries certain risks of object contact. Therefore, it is essential to find methods that minimize risk while ensuring high quality. In this study, the dimensions of the replicated object are approximately 90x30x30mm. Data were captured using a structured light 3D scanner, then imported into an SLA 3D printer. SLA technology provides high printing precision, and the use of PE-like material offers advantages such as chemical resistance and high toughness, making it more durable than conventional resin materials. The 3D-printed replica closely resembles the original in terms of fine details, and its stable material properties reduce the need for additional processing. 3D printing technology shortens the restorer’s working time, allowing them to focus more on addressing the object's deterioration and maintaining its stability. Additionally, 3D printing enables multiple, consistent reproductions without deformation, eliminating issues with mold deformation in casting. The digital files are also easy to transfer, facilitating remote communication to verify details
