The use of 3D printing technology in the construction sector is gaining momentum because it requires no molds, is an automatic and quicker production system, uses less material, and is a more sustainable construction method. However, one of the main difficulties with this method is the placement of reinforcements that can withstand the tensile stresses in the concrete. In this respect, it is believed that the use of continuous textile reinforcement will take 3D concrete printing technology a step further. In this study, the effects of production method (printing and casting), fiber material (AR glass and carbon), coating material (epoxy and Styrene-Butadiene Rubber (SBR)) and type of binding (counterlaid-tricot and pillar) on the flexural performance of cement-based materials were investigated by 3-point bending test. The results showed that different properties of textile reinforcement did not affect the first crack strength of the printed concrete. On the other hand, carbon fiber and epoxy coating absorbed more energy than AR glass and SBR coating.
