Study of Behavior of Beams from 3D Printing Formwork

Abstract

Nowadays, Architectural designs are various and complex. Construction workers often faces problems in setting up formwork to construct the structural parts such as curved beams and free-form beams that are difficult to construct. 3D printing has play an important role in construction technology because it can print various workpieces. Therefore, this research aims to study the flexural behavior of concrete formwork beams produced from 3D printing technology by considering the strength properties of simple beams. The frame was printed with Fused Deposition Modeling (FDM) technology, in which the concrete is stacked to form a frame. In this research, 3 types of frames were varied with 3 different heights of each printing layer: 15.0 mm height (BH1.50), 17.5 mm (BH1.75) and 20.0 mm (BH2.00). The failure of the beams are observered. Then, the test results will be analyzed and compared with normal reinforced concrete (NB) beams.
