Unlike the current layered extrusion 3D printed concrete technology, Concrete Printing in Granular Medium (CPGM) extrudes concrete within a granular medium, which enables greater freedom in printable geometry without being limited by gravity constraints. The primary aim of CPGM is to facilitate the rapid fabrication of intricate concrete elements by removing the stacking process involved in layered extrusion. This project develops the design and fabrication workflow of the CPGM method and presents a case study involving creating a scaled model of a single-objective optimized concrete frame structure.
