Creación de réplicas de patrimonio escultórico mediante reconstrucción 3D e impresoras 3D de bajo coste para uso en entornos educativos

The process of making replicas of heritage has traditionally been developed by public agencies, corporations and museums and is not commonly used in schools. Currently there are technologies that allow creating cheap replicas. The new 3D reconstruction software, based on photographs and low cost 3D printers allow to make replicas at a cost much lower than traditional. This article describes the process of creating replicas of the sculpture Goslar Warrior of artist Henry Moore, located in Santa Cruz de Tenerife. To make this process, first, a digital model have been created using Autodesk Recap 360, Autodesk 123D Catch and Autodesk Meshmixer MarkerBot MakerWare applications. Physical replication, has been reproduced in polylactic acid (PLA) by MakerBot Replicator 2 3D printer. In addition, a cost analysis using, in one hand, the printer mentioned, and in the other hand, 3D printing services both online and local, is included. Finally, there has been a specific action with 141 students and 12 high school teachers, who filled a questionnary about the use of sculptural replicas in education.El proceso de elaboración de réplicas de patrimonio ha sido tradicionalmente desarrollado por organismos públicos, empresas o museos y no es de uso corriente en centros escolares. Actualmente existen tecnologías que permiten realizar réplicas de una manera muy económica. Los nuevos programas 3D basados en la reconstrucción a partir de fotografías y las impresoras 3D de bajo coste, permiten realizar maquetas del patrimonio con un importe muy inferior al tradicional. En este artículo se describe el proceso de creación de una réplica de la escultura El Guerrero de Goslar del artista Henry Moore, situada en Santa Cruz de Tenerife. Para realizar esta reproducción, primero se han creado modelos 3D digitales utilizando las aplicaciones Recap 360, 123D Catch, Meshmixer y MakerWare. La réplica física, se ha reproducido en ácido poliláctico (PLA) mediante la impresora 3D MakerBot Replicator 2. Además, se incluye un análisis de costes utilizando, por un lado la impresora mencionada, y por otro, servicios de impresión 3D, tanto online como locales. Para finalizar, se ha realizado una acción puntual con 141 alumnos y 12 profesores de secundaria a los que se les ha pasado una encuesta de opinión sobre el uso de réplicas escultóricas en educación

Three-dimensional portrait through the use of low-cost digital manufacturing technologies in educational environments

The study and representation of the shapes associated with the human body and the portrait is a part of the curriculum of the subjects of plastic, visual and audiovisual education in secondary education. Currently, the exercises are performed using traditional artistic techniques and in most cases in two-dimensional supports. When it comes to creating three-dimensional models, often it is used clay or other molding elements and construction techniques. This implies the need to have the specific materials and tools to elaborate them. In this article, an activity is presented for the creation of digital and physical three-dimensional portraits, whose objective is that it can be carried out in secondary education centers. For this, low-cost 3D technologies will be used that do not require specific training, accessible for teachers and students. This activity has been carried out with two groups of teachers and students during the academic year 2015-2016. The results shows that this activity is feasible in a school environment and that 3D portraits can be obtained at low cost.</p
