“…3D Capitals (http://librarylivinglab.cvc.uab.cat/home/capitals) is an ongoing project led by the Computer Vision Center (CVC) and the UAB that contributes to giving answers to one of the challenges that research centers currently face -technology transfer with social value, a notion comprised in the Responsible Research Innovation framework (Owen, Macnaghten, and Stilgoe 2012;Stilgoe, Owen, and Macnaghten 2013;von Schomberg and Blok 2020). Digital humanities are becoming a fertile field of experimentation in this direction, and various projects are testing the use of 3D modeling and printing technologies in order to revalue the public cultural heritage and disseminate it to society (Ackerman and Glekas 2017;Merchán et al 2019;Scopigno et al 2017). In this context, the CVC, together with the Sant Cugat Museum and the Library Living Lab, launched an Open Citizen Science project in 2018 with the aim of digitalizing the 144 capitals of the Sant Cugat del Vallès monastery cloister, which are a masterpiece of European medieval art representing biblical scenes, plant motifs, fantastic animals, and delicate geometric figures.…”

Public libraries have proven for centuries to be infrastructures both stable enough as reference centers for access to knowledge yet plastic enough to respond to the social changes of the communities they serve. In these present times of transformation, during which digitalization and the intensive use of technologies are modifying the way in which knowledge is produced, public libraries are facing new and disruptive challenges. The emergence of certain innovation ecosystems within libraries, which place the community at the center of cocreation and codesign processes between different agents, has transformed some public libraries into encountering spaces. The Library Living Lab, in the Miquel Batllori Public Library of Sant Cugat del Vallès (Barcelona, Spain), is an expression of this systemic change. The following paper is a case study based on that sociotechnical infrastructure and analyzes, through two singular examples, how digital technologies can be drivers of social transformation when citizen engagement is placed at the center of innovation processes. The case study also provides insights into how public libraries may become key agents in fostering and strengthening social cohesion through situated, collective, and technology-based innovation practices.

“…The use of these digitalized data for applications related to reverse engineering is added to all the applications already mentioned (Fatuzzo, Sequenzia, & Oliveri, 2016;Sequenzia, Fatuzzo, & Oliveri, 2021). Digital photogrammetric surveys and also the data acquired by the use of handheld scans are so accurate that they permit the recreation and replacement of lost fragments using 3D printing techniques, or the manufacture of moulds to reproduce replicas at different scales (Henriques, Bailão, Rocha, & Costa, 2020;Merchán, Merchán, Salamanca, Pérez, & Nogales, 2019). Thus, this technique is ideal for generating extensive databases of 3D elements which classify existing details in different plasterworks located in different places.…”

Highlights: The photogrammetric survey demonstrates to be a potential tool in the preventive conservation of ancient plasterworks. The high-precision 3D model allows the study and quantification of alterations (e.g. fissures, deformations, and loss of mass or polychromies). The virtual model and the analysis performed with CloudCompare software provide fast, accurate and accessible results to experts in the field. Abstract: Previous studies and documentation about the state of conservation of architectural or decorative elements are crucial for heritage managers, technicians and researchers to succeed in the maintenance and preservation of the heritage. In this sense, hand tracings, digital drawings, or photographs have traditionally been the methods for alteration and sample mapping. In spite of their effectiveness, these methods have some disadvantages, such as the need for more precision in terms of location, dimensions, quantification and types of alterations. By contrast, high-resolution three-dimensional (3D) models allow us to analyse decorative ancient plasterworks with great precision, offering considerable advantages over traditional tools for heritage documentation. To facilitate stakeholders’ work and enhance the quality of data collected, this work proposes the use of photogrammetry as a tool for the documentation of polychromed ancient plasterworks, taking the upper frieze of the access door to the Charles V ceiling room in the Royal Alcazar of Seville as a case of study. Thus, the work methodology applied has shown several advantages over previous methods. On the one hand, it was possible to obtain a 2D planimetry from the 3D model; this is an essential step for those responsible for heritage, especially in reports prior to restoration interventions. On the other hand, the 3D model created enables present alterations identification, the location of fissures and cracks in their three dimensions (opening, length and depth), deformations measurement and control, the quantification of mass or polychrome loss, and the detached elements digital reconstruction. In this way, highprecision digital results are quickly obtained and accessible to all the experts involved in the heritage conservation and maintenance plan.

“…In particular, recent advancement in high technology has led to several attempts in digital technology-based contactless replication to solve the issues of complex processes of the conventional contact method of replication and minimize secondary damage to artifacts (Di Franco et al, 2015;Merchán et al, 2019;Jo et al, 2020a). Byun et al (2009) and Ahn (2017) printed threedimensional (3D) scanning results of artifacts, colored them and treated their surface to complete the replication.…”

To extend the application of digital technology to the replication of artifacts, meticulous details of the process and the diversity of three-dimensional (3D) printing output materials need to be supplemented. Thus, in this study, a bronze mirror with Hwangbichangcheon inscription was digitalized by 3D scanning, converted into a voxel model, and virtual conservation treatment was performed using a haptic device. Furthermore, the digital mold of the bronze mirror completed by Boolean modeling was printed using a 3D sand-printer. Such contactless replication based on digital technology reflects the stability, precision, expressivity, collectivity, durability, and economic feasibility of artifacts. Its application can be further extended to cultural products as well as such areas as education, exhibition, and research. It is expected to be in high demand for metal artifacts that require casting. If empirical studies through experimental research on casting are supplemented in the future, it could extend the application of digital technology-based contactless replication methods.
