From screen to study model
Accurate documentation is the foundation. Because the survey data is metric, it can return into physical form.
Documentation produces a highly accurate digital mesh through photogrammetry. Because this survey data is metric - recording exact physical dimensions and spatial relationships - it can be translated back into physical objects.
Physical study models allow researchers, students and practitioners to examine architectural relationships directly in three dimensions, independent of a screen. We use two primary 3D printing technologies to achieve this translation from photogrammetry to physical model.
Fused Deposition Modeling (FDM)
Fused Deposition Modeling (FDM) is used for rapid prototyping and structural volume studies. It allows for the cost-effective production of larger architectural study models, making it highly suitable for educational environments and workshops where physical massing needs to be evaluated quickly.
Stereolithography (SLA)
For high-resolution architectural detailing - where the documentation must capture fine mouldings, sculptural articulation and weathering patterns - we utilize Stereolithography (SLA) printing. SLA is capable of reproducing the precise surface geometries captured by the photogrammetric mesh.
Case Study: Narthamalai
The Vijayalaya Cholisvaram temple at Narthamalai was printed using SLA technology. The resulting physical model faithfully reproduced the complex geometry of the structure, allowing the unusual architectural arrangement of the circular sanctum within its rectangular envelope to be analyzed as a physical object.
Case Study: Arunkulam
Similarly, the documentation of Arunkulam was translated into a physical study model using SLA. The high resolution of the print ensured that the architectural evidence recorded on-site remained legible in the scaled reproduction.
Future Capability: SLS
While FDM and SLA are currently employed for study models, Selective Laser Sintering (SLS) remains a future capability for producing complex architectural replicas without the need for support structures, offering further possibilities for translating survey data into physical evidence.
