This study explores how 3D printing technologies can be utilized for the preservation and reproduction of ancient cities in Antalya. Historical sites are at risk of deterioration due to natural factors and tourism, necessitating new preservation methods. Through 3D scanning, modeling, and printing, cultural heritage can be digitally archived and physically replicated. This approach offers benefits for restoration projects, museum exhibitions, and educational purposes. The findings indicate that 3D printing technology is an effective tool for preserving cultural heritage and disseminating it to broader audiences. 3D technologies hold significant potential for the sustainable preservation of Antalya’s cultural heritage. In this context, 3D digital models of ancient urban structures in Side, Sillyon, Patara, Olympos, Termessos, Perge, Aspendos, Kaleiçi, and Pednelissos have been created and integrated with geographical data. Some of these ancient cities have been digitized and modeled through 3D printing. In conclusion, supporting cultural heritage with contemporary preservation approaches has become a strategic necessity—not only for safeguarding the past but also for strengthening collective identity and enhancing educational and tourism potential. Accordingly, the preservation efforts of Antalya’s ancient cities, supported by digital tools and 3D printing, serve as an exemplary model for the transmission of cultural heritage to future generations.
