Abstract

Using a material extrusion 3D printing technology, we fabricate beams with axial rebar and subject them to four-point flexural tests. Beams were fabricated using fiber-reinforced cementitious composite by both 3D printing and formwork casting methods, and their structural performance were compared. The printed specimens demonstrate load bearing and deformation capabilities equal to or greater than those of cast specimens, with maximum loads exceeding values calculated by existing design formulas. The printed specimens also show good crack dispersion and confirm that the proposed manufacturing method adequately ensures bond characteristic between rebar and printed element.
