Heritage 4.0: How Applied 3D Technologies and Digital Twins Are Redefining Cultural Preservation Beyond Replication

This work examines how digital technologies, particularly 3D imaging, additive man-ufacturing, and digital twins, contribute to a more interactive and process-oriented understanding of cultural preservation. Building on practical experience with museum scanning and 3D reproduction, the study introduces the Heritage 4.0 Cycle, a conceptual framework that structures digital heritage management into four iterative phases: Capture, Curate, Connect, and Co-create. The model integrates technological, ethical, and social aspects of preservation, describing how cultural heritage operates as a living system supported by data, interpretation, and participation. Findings indicate that 3D technologies function as mediators between tangible and intangible heritage, promoting inclusivity, collaborative learning, and sustainable engagement. The framework aligns digital preservation practices with broader objectives of education, innovation, and community development. By formalizing Heritage 4.0 into a structured and iterative framework, this study contributes a transferable model that supports sustainable and smart cultural ecosystems by aligning digital documentation, ethical curation, participatory engagement, and digital twin-enabled connectivity within a coherent heritage management strategy
