Abstract: A 3D printable clay-based mortar cementitious ink includes a blend of commercially available Portland cement, calcium carbonate, sand, and calcined clay. The calcined clay is produced from the calcination of clay having a high kaolinite content of greater than about 60%. The clay is calcined at a temperature of between about 600° C. and about 800° C., preferably between about 650° C. and about 850° C., for a period of one to two hours. In a preferred embodiment, a ratio of calcined clay to Portland cement is about 0.148, a ratio of calcium carbonate to Portland cement is about 0.333, and a ratio of sand to Portland cement is approximately about 3.0. The ratio of water to powder (clay, cement, calcium carbonate, and sand) may range between 0.39 and 0.40.
