In the last decades, digital fabrication technologies have stimulated the materialization of complex and customized solutions in several materials. Recently, the integration of these technologies with such a variable and rich material as concrete has prompted an explosion of possible processes and outcomes for digitally fabricated concrete structures. In this context, this paper examines current digital fabrication strategies for concrete, focusing on their applications and in identifying critical issues for their adoption. From this point, through the presentation of two case studies, we propose and discuss Robotic Hot Wire Cutting as a technically and tectonically relevant digital fabrication technology for customized concrete architecture.
