The context of digital fabrication allows architects to reinvestigate material, process and the design decisions they entail to explore novel expression in architecture.This demands a new approach to design thinking, as well as the relevant tools to couple the form of artefacts with the process in which they are made.This paper presents a customised computational design tool developed for exploring the novel design space of Concrete Extrusion 3D Printing (CE3DP), enabling a reinterpretation of the concrete column …
