TY - JOUR AU - Vranich, Alexei PY - 2018 DA - 2018/12/13 TI - Reconstructing ancient architecture at Tiwanaku, Bolivia: the potential and promise of 3D printing JO - Heritage Science SP - 65 VL - 6 IS - 1 AB - The ruins of Tiwanaku (A.D. 500–950), in the modern republic of Bolivia, present an archaeological challenge owing to intense looting during the colonial period that effectively demolished the site. One building in particular, known as the Pumapunku, was described by Spanish conquistadors and travelers of the sixteenth and seventeenth centuries, as a wondrous, though unfinished, building with gateways and windows carved from single blocks. Unparalleled in the pre-Colombian New World, the craftsmanship of this masonry has long been considered the architectural apogee of Andean pre-Colombian lithic technology. Unfortunately, during the last 500 years, treasure hunters have ransacked this building to the point that none of approximately shattered remains of 150 blocks of the standing architecture are to be found in their original place. Over the last century and a half, several different scholars have carefully measured the shattered architecture and even managed to join several fragments to form complete pieces. This research revisited these historic field notes with a view to transforming this century and a half of documentation into solid 3D form. These measurements were entered by hand into an architectural modeling program; the virtual form was subsequently printed in 3D form at 4% reduced scale. Unlike large architectural pieces — or notes or models on a computer screen — 3D-printed pieces can be manipulated quickly and intuitively, allowing researchers to try combinations and seek connections rapidly, turning over pieces and testing possible fits. This tactile engagement, along with the ability to quickly try out combinations of the 3D-printed pieces, led to fresh and often unexpected insights. Once refined and simplified, this methodology, was demonstrated to the indigenous site managers who were provided with a full copy of the printed architectural fragments with a view to continuing research and to present the work to visitors, stakeholders and other scholars.
