Digital Surface Documentation and Accessible Replication of Everyday Heritage: Integrating Surface Characterization, Additive Manufacturing, and XR Technologies

Everyday heritage objects are often overlooked despite their cultural significance and vulnerability to surface degradation caused by environmental exposure, material ageing, and human interaction. This review examines how surface characterization, digital documentation, additive manufacturing, and extended reality (XR) technologies can be integrated to support the conservation, replication, and inclusive dissemination of such assets. The study synthesizes recent advances in non-destructive surface analysis methods, including spectroscopic and imaging techniques, alongside 3D scanning approaches capable of capturing both geometry and surface condition. These data are linked to additive manufacturing workflows for producing accurate and durable replicas, with particular attention to surface fidelity and material selection. The review further explores how tactile replicas and multimodal interpretation strategies can enhance accessibility for visually impaired users, addressing limitations of visually dominant heritage practices. XR technologies are discussed as complementary tools for interpretation and remote access. The findings highlight that combining surface-focused conservation with digital and fabrication technologies enables more resilient, accessible, and sustainable heritage management. Future research should focus on standardizing inclusive design approaches and improving the integration of surface data into digital and physical reproduction pipelines.
