“…Based on this, the finite element procedure is adopted to find the elastic moduli for a particular mesostructure of the FDM processed part. In the present work, the ABS polymer filament material properties available in [3] are employed in the FE analysis.…”

“…Therefore, it is important to estimate the final properties of a material for effective analysis of the part. Studies are available on experimental work to find the elastic moduli of the material of an FDM processed part [2][3][4][5]. The effect of process parameters and building strategies on the mechanical properties of a part have been the main focus in research so far.…”

“…The bond formation among the roads is driven by thermal energy of the extruded material [9]. Researchers [2][3][4][5][6][7][8][9][10][11][12][13] discussed the various process parameters of FDM such as raster orientation, air gap, bead width and temperature effect on the mechanical properties of the final fabricated part. The raster angle was observed to have more influence on the mechanical properties than other parameters.…”

“…Ahn et al [26] employed analytical models of classical laminate theory and the Tsai-Wu failure criterion for laminate to investigate the failures in the FDM parts. Li et al [3] presented a theory based on void density to calculate elastic moduli of a layer and the results are validated experimentally and also mechanical behavior of the parts characterized using laminate theory. The elastic moduli for FDM processed layers (orthotropic material) are found experimentally by Casavola et al [27] and then classical laminate theory is employed to characterize the mechanical behavior of the FDM processed parts.…”

Abstract:In the present study, the mesostructure of a fused deposition modeling (FDM) processed part is considered for the investigation of its mechanical behavior. The layers of FDM printed part behave as a unidirectional fiber reinforced laminae, which are treated as an orthotropic material. The finite element (FE) procedure to find elastic moduli of a layer of the FDM processed part is presented. The mesostructure of the part that would be obtained from the process is replicated in FE models in order to find stiffness matrix of a layer. Two distinctive architectures of mesostructure are considered in the study to predict the mechanical behavior of the parts. Also, influences of layer thickness, road shape and air gap on the elastic properties of a material are investigated. Further, the parts fabricated with FDM process are treated as laminate structures. From the numerical results, it is seen that the elastic moduli are governed by mesostructures. Our laminate results are validated with experimental to demonstrate the use of classical laminate theory (CLT) for FDM parts. The elastic moduli (E 1 , E 2 , G 12 , ν 12 ) of a layer used in the analysis are calculated from FE simulations. This study establishes relationship between mesostructure and macro mechanical properties of the part.

Recent advances in multi-material 3D and 4D printing (time as the fourth dimension) show that the technology has the potential to extend the design space beyond complex geometries. The potential of these additive manufacturing (AM) technologies allows for functional inclusion in a low-cost single-step manufacturing process. Different composite materials and various AM technologies can be used and combined to create customized multi-functional objects to suit many needs. In this work, several types of 3D and 4D printing technologies are compared and the advantages and disadvantages of each technology are discussed. The various features and applications of 3D and 4D printing technologies used in the fabrication of multi-material objects are reviewed. Finally, new avenues for the development of multi-material 3D and 4D printed objects are proposed, which reflect the current deficiencies and future opportunities for inclusion by AM.

Polylactic acid (PLA), despite its widespread use in three-dimensional (3D) printing technique, is lacking in the literature on creep behavior due to the printing parameters. Also, the potential use of carbon fiber-reinforced composites as 3D printing materials is remarkable as it improves mechanical properties of the produced parts. Therefore, it is important to find out the positive/negative effects of composite filaments on creep strength. The main purpose of this research is to examine the creep behaviors of PLA and PLA composite produced with 3D printer and to reveal the effects of the printing parameters on the short-term creep.
