Resumo

3D printing in cement-based materials requires a substantial amount of non-renewable raw materials to conduct tests and adjust the rheology of mixtures intended for additive manufacturing. In this context, the use of laboratory small-scale printing systems, such as the delta system, can optimize compositions and ideal configurations for large-scale printing. Due to the viscoelastic nature of clay, its rheological characteristics are similar to those of cementitious materials suitable for extrusion, offering a viable alternative for obtaining additional printing parameters for different paste consistencies. The overall objective of this research proposal is to evaluate the rheological properties of different types of clays in the context of 3D printing and to obtain printing parameters for cementitious materials using delta printing systems. The methodology involves four key stages: 1) Preparation and characterization of three types of clay with varying moisture contents, using techniques such as SEM, XRF, and setting time; 2) Rheological evaluation of the clays through tests including squeeze flow and extruder rheometry; 3) 3D printing tests to determine the buildability of the samples, using a 6 cm diameter cylinder as a reference; 4) Optimization of printing parameters, including the selection of nozzles, extrusion speeds, and layer heights tailored to each clay type and moisture content. The results obtained from the tests demonstrated that the printing parameters derived from different types of clay and consistencies allowed for the successful 3D printing of cementitious composites with similar consistencies and characteristics in delta systems. Thus, rheological characterization as a technique for defining mixture parameters in printing, as well as its relationship with the physico-mechanical properties of clay and cement composites in the hardened state, will provide the necessary parameters for large-scale additive manufacturing.
