[EN] This paper focuses on the use of 3D printing as a tool for the dissemination of Maya architectural heritage. The case study is the Acropolis of La Blanca, the main complex of this archaeological site located in the Peten department, Guatemala. One of the objectives of La Blanca Project was to create a model of the Acropolis as part of the strategy for dissemination and as a didactical resource for the Visitor Center. The documentation of this architectural complex with digital survey techniques allowed to obtain a high-fidelity model of the Acropolis¿ buildings. In order to achieve this goal, it was necessary to develop a methodology for the reverse modelling of the Acropolis, starting from the data obtained by laser scanning. We developed a workflow to create a virtual replica of the Acropolis optimized for 3D printing. This model was first printed in 17 parts by using the FDM technology. Then, it was transported to Guatemala and, finally, it was reassembled and placed at the Visitor Center. Today, this physical replica of the Acropolis is an important resource that allows the visitors to have a complete view of the main complex of the site, which is not easy in the Guatemalan jungle. It also provides an exclusive view of some parts of the Acropolis, already studied by researchers and now protected with a soil layer to ensure their preservation. Moreover, it is a useful resource for supporting dissemination and also serves as a teaching resource for student visitors., This work was funded by the Universitat Politècnica de

[ES] La adaptación de los mayas postclásicos a las nuevas condiciones de vida surgidas a raíz de la crisis generalizada del final del
período Clásico mediante respuestas resilientes se ha convertido en un tema de creciente interés por parte de los investigadores mayistas en las últimas décadas. El estudio de vestigios arqueológicos adscritos al Postclásico puede ayudar a entender
por qué ciertas tradiciones fueron abandonadas, mientras que otras han perdurado a lo largo del tiempo, como es el caso de
las ceremonias del culto a la lluvia. Ejemplo de ello son los hallazgos de ofrendas y otros vestigios arquitectónicos realizados
en Chilonché, un antiguo asentamiento urbano maya fundado en la cuenca del río Mopán (Petén), cuya arquitectura y manifestaciones artísticas son un fiel exponente de la importancia política que tuvo el sitio en su dilatado período de ocupación. Los
resultados de esta investigación, que combina los estudios arqueológicos y arquitectónicos con los análisis arqueométricos e
iconográficos de las piezas cerámicas exhumadas, permiten afirmar que las ofrendas postclásicas halladas en un palacio de la
acrópolis de Chilonché están íntimamente ligadas al acto de verter agua y a la imagen de Chaahk, y por lo tanto a rituales
vinculados a la lluvia., Los autores agradecen el patrocinio del

[EN] Excavating an ancient Maya city requires a long-term archaeological project that entails adequate documentation procedures for the unearthed remains, frequently of monumental scale and with difficult preservation conditions. A digital laser scanner survey methodology was designed and implemented to document the exposed architecture and to follow-up the archaeological excavation of the Maya site of La Blanca (Peten, Guatemala). All scans collected during the different field seasons were stored and aligned in a common reference system. Thus, an accurate digital three-dimensional database was obtained, including all the architectural remains found, some of which had to be reburied to ensure their preservation. The resulting database is a helpful repository that facilitates to extract all the graphic outputs required for: planning the next excavation campaigns, monitoring the preservation of the buildings, studying the architecture and construction technology in detail, and disseminating the excavation results. This paper describes the methodology and procedures used to build-up this database., The work for this article has been carried out in the project Arquitectura maya. Sistemas constructivos, estética formal, simbolismo y nuevas tecnologías (PGC2018-098904-B-C21) which is funded from the Spanish Ministry of Science, Innovation and Universities. It was also supported by Universitat Politècnica de València under the Research and Development Grants Program (PAID-01-17); Generalitat Valenciana and European Social Fund (APOSTD/2020/004) and the Santiago Grisolía grants program (GRISOLIAP/2018/139).
