Valorizzazione del Patrimonio storico mediante pratiche di modellazione digitale e stampa 3D

This thesis explores the role and evolution of physical architectural models, focusing on their function, applications, and conceptual implications in relation to digital tools. In an era dominated by virtual imagery, physical models have been largely replaced by digital scenarios that allow faster spatial visualization. However, the growing need to reproduce reality in three dimensions invites a reconsideration of the boundary between real and digital. Despite technological advances, the physical model remains a key tool for communicating architectural heritage and archaeological artifacts, offering immediate, tangible understanding to diverse audiences. Thanks to 3D printing, it is now possible to produce accurate models from integrated digital surveys, using variousmaterials to enhance heritage valorization at differentscales. The research develops a methodological process that moves from survey to printed model, with practical applications ranging from urban landscapes to detailed full-scale reproductions. The study examines the transition from physical to digital and back, exploring concepts like representation scale, level of detail, reverse modeling, and rapid prototyping. Through various case studies, the research investigates surveying techniques, database management, mesh con struction, and 3D printing workflows, from material selection to model partitioning and assembly. These practical experiments highlight the potential of physical models in heritage promotion and knowledge dissemination. The thesis concludes with reflections on the integration of digital and tangible models to create interactive experiences. Participation in several European projects has provided opportunities to test the use of VR, AR, and video mapping, demonstrating how digital tools can enhance multisensory interactions with physical models. By adding colorimetric, morphological, and cultural information, these technologies make cultural heritage more accessible, expanding the comprehension of spaces and objects through immersive representations.
