This project utilizes additive manufacturing techniques to reproduce marble statues, requiring high-resolution 3D models for support. The project utilizes SfM and FDM techniques to produce reality-based models and 3D print replicas.
A project for realizing replicas of a couple of marble statues starting from reality-based 3D models is being presented in this paper. On the crowning element of the baptistry, consecrated to San Giovanni in Corte in Pistoia (Italy), there were originally a couple of marble statues that, in the 1980s, were removed to preserve them better and to avoid security issues. Recently, the Superintendence started a project aimed to reproduce both statues with additive manufacturing techniques. High-resolution 3D models are required for supporting the replica process. This project takes advantage of the structure from motion (SfM) technique to produce reality-based models and fused deposition modeling (FDM) to 3D print the replicas. This paper presents an overview of the potential of additive manufacturing systems in the field of cultural heritage conservation and describes all the phases of the project, up to the evaluation of the correspondence between the original and the copy.
