This study investigates the application of 3D scanning and printing technologies for reconstructing missing parts of a historical glazed pottery piece from the Middle Islamic centuries, discovered during archaeological excavations in the Tabriz Bazaar, Iran. The research aims to evaluate the compatibility of this digital workflow with core conservation principles: reversibility, minimal intervention, distinguishability, and legibility. A blue-and-white sherd with red paste and extensive damage (over 46% missing volume) was selected. The methodology included descriptive, graphical, and photographic documentation, 3D laser scanning (Rexcan CS), virtual reconstruction using SolidWorks, and FDM printing (Prusa i3 with PLA filament). Results showed that the digital approach enabled precise, contactless reconstruction, avoiding direct molding risks. The missing portions were printed slightly undersized to accommodate adhesive and attached reversibly with Paraloid B-72. Color reintegration was completed using acrylic tones, respecting distinguishability. The study concludes that 3D technologies offer an efficient, flexible, and ethical solution for reconstructing complex ceramic artifacts, provided that subsequent steps like color toning follow theoretical restoration frameworks.
