3D Heritage: Reality Capture and Large-Scale 3D Printing—a 2-Way Road

Industry Talk  ·  Las Vegas  ·  2017

Much of the world's heritage nowadays is at risk from destruction by climate change, natural disasters, war, or the simple passing of the years. 3D printing technology presents a unique opportunity in a way not seen before by offering the possibility of physically recreating any design imagined. ACCIONA has successfully proven what can be done with 3D technology through the building of the first 3D printed bridge in the world (http://www.3ders.org/articles/20161214-spain-unveils-worlds-first-3d-printed-pedestrian-bridge-made-of-concrete.html). Having learnt extensively from this past experience, this time around we are taking the social turn. In conjunction with the Spanish National Archeological Museum(MAN),ACCIONA will give historical monuments a new look, both digitally and physically, by the capturing and digital rendering of a collection of 32 Medieval pieces that are exposed in MAN through the use of Autodesk Recap360, creating digital 3D models through photogrammetry. This collection of art will be then exposed through a visualization platform and a big TV screen with which visitors can interact and learn. In addition, this project is an immense opportunity to showcase the amazing possibilities behind 3D printing technology, in this case by being applied to the recreation of world heritage monuments. This will be done through the printing of the arch of San Pedro de Dueñas (León),a structure of great historical and cultural significance in Spain, which will be exposed outside the museum for all to see. One of the reasons this structure was chosen was because of its complexity, thus providing an excellent opportunityfor 3D printing to present its credentials. To replicate this element several technologies are going to be used: first of all Large Scale 3D printing (or additive manufacturing) for manufacturing architectural elements with no high detail needed; secondly sculptural element are going to be manufactured using a milling robot (subtracting manufacturing method). All the elements manufactured are going to be exhibited at the front ofSpanish National Archeological Museum for 6 months, in the center of Madrid. Autodesk manufacturing and designing software for 3D Printing will be used for this purpose. Our commitment in this project (we call it “3D Heritage”) is to probe, as it is known, that conventional construction techniques stump onto the issue of complex designs due to their inability to mold and adapt to free-form, something 3D printing thrives in, helping Culture and Historical Heritage to be preserved. .
