The subject of this thesis pertains to current digital fabrication and CAM (computer aided manufacturing) techniques in architecture. It is a response to the current condition of architectural fabrication in which design processes occur largely via digital means and construction techniques are still reflective of hand-made, manufactured, or hand-assembled processes. This thesis aims to answer the following question: How can complex computer aided design processes be better implemented by thinking of the design-fabrication process as a whole rather than as separate practices? Subsequently, this question will be explored through a bespoke design for a digital mould, which maintains the digital design intent allowing the author to maintain control of the exploration and final iteration of the work. Through the use of the digital mould, this thesis will explore possibilities of feedback between the digital model, and the properties of glass fiber reinforced concrete (GFRC) to create double-curved concrete panels.
