Fused Deposition Modeling (FDM - a technology of additive manufacturing) parts entail a certain amount of ambiguity in terms of its material properties and microstructure due to its manufacturing technique. Therefore, an FDM part differs from its design model in terms of strength and stiffness. With an increasing amount of FDM parts being used as end use products, it is necessary to simulate and analyze them. Due to the differences in microstructure and material properties of FDM parts, it is necessary to determine the accuracy of analysis methods like Finite Element Analysis (FEA) while analyzing the non-continuous, non-linear FDM parts. The goal of this study is to compare FEA simulations of the as-built geometries with the experimental tests of actual FDM parts. A dogbone geometry with different infill patterns is tested under tensile loading. Further, as-built 3D models are simulated using FEA and the stress results are compared with experimental data. This study found that FEA results are not always an accurate or reliable means of predicting FDM part behaviors.

“…In the near future, the group also aims to use rapid prototyping technology for research and development of doubledecker buses or a further vision to localize the design and manufacture of its products. Upadhyay Kshitiz et al [4] presented the experiment with a layer height of 0.254 mm and two directions of sample construction including horizontal X and vertical Z for the purpose of improving mechanical properties through adjusting the parameters of the prototyping process. The above parameter was used by the research team on SST -768 and a rapid prototyping device of FDM technology with ABS P400 material.…”

The additive manufacturing technology based on the principle of material addition is an important technology in product design, manufacturing, and development. In addition, the trend in the recent future of this technology will be a major step to develop in the rapid manufacturing industry. Among the rapid prototyping technologies, the most popular FDM (fused deposition modeling) technology has been widely applied in the practice. The quality of rapid prototyping technology in general as well as FDM technology in particular mainly depends on the parameters in the prototyping and operational process. In this paper, the optimum parameters of the prototyping process based on the FDM technology are identified to improve the tensile strength of 3D printing products with PLA and PLA-copper materials. The parameters are chosen in the process of doing the experiments such as infill pattern, fill density, print speed, and print temperature. Then, based on Taguchi analysis technique, the experimental planning method is employed for design and optimization, with the support of Analysis of Variance (ANOVA) to evaluate and identify the influence of parameters on the tensile strength of the printed hook-shaped product. The results highlighted that the maximum tensile force of the sample is printed with PLA-Copper material with the optimum parameters is infill density of 75%, printing speed of 65 mm/s, and temperature of 185°C.

“…The first step before slicing is to orientate the part, which means how to place the part referred to the printer axis (X, Y and Z). The orientation affects surface roughness and/or dimensional accuracy [2][3][4][5][6][7][8][9][10], printing time [4][5][6] and part strength [7,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

“…Mechanical properties of FFF manufactured parts are difficult to predict mainly because parts present anisotropic mechanical behavior [16,23,25,[42][43][44] and the printing parameters affect their mechanical response, the most studied being: layer height [19,35,39,41,[45][46][47][48][49][50], infill orientation [13,18,21,23,35,44,48,[50][51][52][53][54], infill pattern [13,24,41,46,53,[55][56][57], infill density [13,35,38,41,[44][45][46]49,57], wall thickness [22,23,45] and nozzle diameter …”

In this paper, the fatigue response of Fused Filament Fabrication (FFF) Acrylonitrile butadiene styrene (ABS) parts is studied. Different building parameters (layer height, nozzle diameter, infill density, and printing speed) were chosen to study their influence on the lifespan of cylindrical specimens according to a design of experiments (DOE) using the Taguchi methodology. The same DOE was applied on two different specimen sets using two different infill patterns: rectilinear and honeycomb. The results show that infill density is the most important parameter for both studied patterns. The specimens manufactured with the honeycomb pattern show longer lifespans. The best parameter set associated to that infill was chosen for a second experimental phase, in which the specimens were tested under different maximum bending stresses to construct the Wöhler curve associated to this 3D printing configuration. The results of this study are useful to design and manufacture ABS end-use parts that are expected to work under oscillating periodic loads.
