Abstract: “The first attempts to use additive manufacturing civil engineering are successful. Additive printing can be used to print precast elements, building envelope elements or to print whole structure using contour crafting. The main goal of this research is to be a sort of bootstrap step, allowing us to have a grip on the whole chain of activities, protocols, and tools: creation of computer models of printed parts, 3D printing, mechanical properties testing, raw results storage and processing. The aim of the work was to determine the anisotropy of material behavior in tension for 3D printed materials and preparation the testing protocol for digitally manufactured cementitious building products. Samples for tensile strength determination were printed in FDM technology with three space fill (printing densities) and three different layer orientations.”
