Abstract :The aim of this study was to investigate both experimentally and numerically the moment capacities and elasticities of L-type furniture corner joints with case construction joined by dowels produced in different orientations with three-dimensional (3D) printing technology. The dowels were utilized within the scope of the study were produced by printed in two different orientations (vertical and horizontal) and thus effect of the printing orientation on the performance of the joints was investigated. Two different filament materials, Acrylonitrile Butadiene Styrene (ABS) and Acrylonitrile Styrene Acrylate (ASA), were preferred in the production of dowels. The produced dowels were used as fasteners in L-type corner joints. In the study, a total of 80 L-type corner joint specimens were prepared with 2 different printing orientation (horizontal and vertical), 2 different number of dowels (2 dowels, 3 dowels) and 10 replications of each specimen, and 40 of them were tested under static diagonal tension and the remaining 40 were tested under static diagonal compression load. In addition, numerical analyses were performed for each group by finite element method (FEM). According to the test results, it was observed that the doweled joints produced from ASA gave higher values than the doweled joints produced from ABS material, and the doweled joints produced in the horizontal orientation gave higher values than the doweled joints produced in the vertical orientation. It was also observed that increasing the number of dowels in the joints from 2 to 3 increased the moment capacity and elasticity of the joints. As a result of the study, the numerical analyses performed by the finite element method were found to be consistent with the actual experimental results and observed deformation characteristics in terms of both forces and stresses.
