Özet

Aim of this study is to specify the performance of cross sectional geometries of beams which were experienced the tension stress. These beams which were 3D printed with the same amount of filament have same cross sectional area, length and volume.. Thus, design points were sorted without the effect of the amount of filament, printing time and energy consumption. Geometry of cross section was changed. In contrary length of beams and applied forces were kept constant for all design points. These geometries were selected as, circle, rectangle, equilateral triangle, rhombus (diamond), ellipse and rounded rectangle. Moreover four different printing material were taken into consideration for comparison according to tension. Depending on 6 different cross sectional geometry, 101 cross sectional area and 4 different material, 2424 design alternative were created in total. At the beginning mathematical model of these designs were constructed, then they were tested by using finite element method (FEM) and regression analysis. All model branches were compared to each other with the statistical analysis. As a result of all analyses, design alternatives were sorted according to stress and deformation performance.
