Abstract
The aim of this study is the development of a hybrid pattern for 3D printed object via Fused Deposition Modeling Technique (FDM). In the previous study, a tensile test simulation was applied to the specimens with linear, hexagonal and diamond infill patterns. These patterns were designed with 50% infill density. Nodal displacement was applied as 0.04 mm to specimens as 8 steps to create realistic tensile test simulation. For comparison; the key parameters for structural strength and pattern influence were obtained from the simulation results. Tensile test simulation showed that hexagonal pattern has the lowest degree of occurred stress values and provides highest factor of safety for 50% infill density, when compared with the other type of pattern types. An optimization process was conducted in this study to gain better results for 3D printing by considering the parameters of manufacturing time, material consumption and structural strength. In optimization process, the tensile test simulation results of the specimens with different patterns were taken into consideration. The stress raiser zones (stress concentration) show the maximum occurred stress. They were reinforced with the hexagonal pattern. Clamped section and straight zones were designed with the pattern type of diamond for optimization. The pattern of the hybrid system was created with 64% of diamond and 36% of hexagonal. Structural analyses were applied to designed specimens with hexagonal, diamond and hybrid types of infill patterns. The results showed that manufacturing time and material consumption increased 2 minutes and 0.2 g respectively. 12 % strength and more ductile structure were obtained with hybrid pattern. Therefore, it can be concluded that the developed hybrid pattern is optimum for 3D Printing Technology.
