“…The main materials used to make heels and soles are wood, cork, rubber, leather. The shoes can be made by hand, using various machines, and more recently, 3D printers [9,10]. Starting with the year 2012, additive manufacturing (AM) begins to be applied in this industry [11] by achieving the Cinderella's shoe in a futurist manner, using nylon filament.…”

Generally, the importance of bending test is used to analyse the resistivity effect on its larger face size.Comparatively, stress induction is quite large in the perpendicular face to the point of contact of bending load. Therefore the thickness wise maximum stress acting area of bending test specimen must be analysed for the purpose to estimate the breaking point of test specimen, which supported a lot in the life estimation of a component. In this work, three different composites were selected under primary composite materials and underwent bending testing for the purpose of material refinement to tackle compressive load based applications. Ansys Workbench 17.2 is an advancement tool, which is used in this work for composite generation and structural simulations. All the tests were effectively executed with the help of advanced coupling facility between different working environments. Finally, the numerical results were compared with experimental results and then suitable material is optimized. Also, the conventional theoretical formulae were used to validate the flexural outcomes. Further, the advanced finite element analyses simulations were expanded to advanced composites materials. From the above all studies, the superior material was finalized based on the multi-disciplinary optimization outcomes.

Polylactic acid (PLA) is produced from renewable materials, has a low melting temperature and has a low carbon footprint. These advantages have led to the extensive use of polylactic acid in additive manufacturing, particularly by fused filament fabrication (FFF). PLA parts that are 3D printed for industrial applications require stable mechanical properties and predictability regarding their dependence on the process parameters. Therefore, the development of the FFF process has been continuously accompanied by the development of software packages that generate CNC codes for the printers. A large number of user-controllable process parameters have been introduced in these software packages. In this respect, a lot of articles in the specialized literature address the issue of the influence of the process parameters on the mechanical properties of 3D-printed specimens. A systematic review of the research targeting the influence of process parameters on the mechanical properties of PLA specimens additively manufactured by fused filament fabrication was carried out by the authors of this paper. Six process parameters (layer thickness, printing speed, printing temperature, build plate temperature, build orientation and raster angle) were followed. The mechanical behavior was evaluated by tensile, compressive and bending properties.

Fused Deposition Modeling (FDM) is one of the most commonly used 3D printing technologies for creating complex parts from a Computer Aided Design (CAD) model. It is observed that mechanical strength of 3D printed polylactic acid (PLA) parts are affected by various parameters associated with part, process, material and operating conditions. One of the key parameters that influences tensile and flexural strength of 3D printed PLA parts is build orientation. Researchers have investigated the effect of a limited number of build orientations on tensile strength. Moreover, less work has been reported which studies the effect of build orientation on flexural strength. None of the studies modeled tensile load and bending load as a function of thickness and compared tensile loading capacity with flexural loading for different orientations. Therefore, an attempt is made to include a greater number of build orientations that occur during 3D printing of complex PLA parts. Build orientations considered in this study are flat, flat-support, edge, edge-45, upright and upright-45 with three thicknesses i.e., 1.2 mm, 2.0 mm and 2.8 mm. Tensile and flexural tests are performed as per American Society for Testing and Materials (ASTM) standards. Experimental results show that six orientations form two groups i.e., strong orientation group and weak orientation group. PLA appears stronger in tensile loading than bending. Edge orientation is strongest during tensile as well as bending loading whereas upright orientation is weakest in tensile loading and upright-45 orientation is weakest in bending. Force trends, it can be concluded that thickness can be minimized where build orientation belongs to the strong orientation group. Similarly, thickness can be increased where build orientation belongs to the weak orientation group.
