Abstract
The objective of this article is to generate and validate a workflow that allows us to print physical twins (models) from digital twins obtained from unique buildings of our architectural heritage. These physical twins will guarantee the preservation and diffusion of the cultural asset, and will promote new pedagogical ways to spread the heritage. In addition, these physical cufflinks are an interesting tool to guarantee universal accessibility through low-cost and rapid distribution typological models. We can overcome physical barriers and reach many more users, regardless of their economic, physical, or location conditions. To obtain this workflow, digital twins of architectural elements of high cultural value obtained by photogrammetry or terrestrial laser scanner will be used. The digital twin will be optimized through different platforms, and an optimized exchange file will be generated for its dissemination and printing. A digital platform will be proposed that guarantees the free distribution of these digital twins to any user. Finally, the physical twins will be obtained. For the development of this work, we have chosen to use 3D resin printers with SLA technology (selective laser exposure to light by laser) due to their performance and high quality in the models obtained.
