Smart Dynamic Casting (SDC)
The material challenges are numerous, requiring an understanding of chemical admixture control of cement hydration, as well as developing new strategies for processing concrete. This is particularly demanding because of raw material variability and is something that the collaborative project Digital Concrete strives to find solutions to.
From an architectural standpoint, the possibility to create bespoke vertical columns and folded structures in an unbroken digital chain places SDC at the leading edge of real-world realisation of bespoke fabrication of concrete structures. The recent production of façade mullions for DFAB HOUSE demonstrates how important it is to produce full-scale demonstrators to understand how digital fabrication, concrete material science, mechanical engineering and digital design must be joined in an enhanced process to achieve successful results. Each module has been developed in an interdisciplinary context, and has highlighted how important various disciplines are in real-world application of digital fabrication with concrete.
