Abstract

The main goal in this investigation is to develop inexpensive formulations of Portland cement pastes for additive manufacturing using the direct ink writing technique. Kaolin, a superplastificant, and calcium carbonate additions were used as additives and modifiers of the printing material. A total of 3 formulations were developed with acceptable shape stability and finishing of the manufactured parts. Cylindrical samples of 17 mm in diameter and 26 mm of height were built in order to be tested in compression tests. The microstructure was characterized with scanning electron microscopy, density, and compression tests. Results showed one formulation to be the best one, which was associated mainly to an optimal kaolin content as rheology regulator.
