“…These described printing parameters are only two of the several possible settings that can be chosen in the process. These values significantly affect the mechanical tensile, compression and flexural properties of the printed elements (Yadav et al, 2020;Yao et al, 2019). The main parameter values were set thanks the experience gained by the authors in past works about the FDM technology.…”

“…Due to the intrinsically limited mechanical properties and functionalities of printed pure polymer parts, there is a critical need to develop printable polymer composites with high performances (Wang et al, 2017). The influence of some process parameters (layer height, extrusion temperature and material density) on the tensile strength of FDM 3D printed specimens was studied by Yadav et al (2020) Several materials were investigated, e.g., PETG, ABS and multi-materials including 60% ABS + 50% PETG. Several combinations of materials and process parameters were studied using the ASTM D638-(IV) standard test specimen.…”

In recent years, the 3D Fused Deposition Modelling (FDM) technology, usually employed for the production of nonstructural objects, has been also used by the present authors for the production of small structural elements where the applied loads are moderate. A typical application could be the production of small Unmanned Aerial Vehicles (UAVs) where stresses are not excessive. In these cases, the FDM technique can use polymers such as Acrylonitrile Butadiene Styrene (ABS) and PolyLacticAcid (PLA). The present work is an extension of a past authors' work where some sandwich configurations were proposed combining different materials (ABS or PLA) and different cores (homogeneous or honeycomb). In the present study, only PLA specimens embedding honeycomb cores are analyzed in order to understand if this selected lamination scheme could lead to an important weight reduction without significant decreases of mechanical properties. A capability analysis is performed on the geometrical parameters of the specimens (also comprising the weight) in order to investigate the stability of the printing process. A three-point bending test is conducted to evaluate the linear bending Young modulus and the ultimate bending stress. These mechanical properties are post-processed in order to conduct a capability analysis to propose the upper and lower specification limits to be used with confidence in appropriate structural analyses.

“…However, the mechanical properties of printed pure polymeric elements remain low and there is an important necessity to develop new printed polymer composites having higher performances [24]. For these reasons, Yadav et al [25] analyzed how the main FDM parameters influenced the tensile strength of ABS, PETG and multi-materials constituted by ABS and PETG. The main investigated parameters were extrusion temperature, layer thickness and material density.…”

In this paper, polymeric specimens are produced via the Fused Deposition Modelling (FDM) technique. Then, experimental tensile and compression tests are conducted to evaluate the main mechanical properties of elements made of PolyLacticAcid (PLA) material. A standardized characterization test method for FDM 3D printed polymers has not been developed yet. For this reason, the ASTM D695 (usually employed for polymers produced via classical methods) has been here employed for FDM 3D printed polymers after opportune modifications suggested by appropriate experimental checks. A statistical analysis is performed on the geometrical data of the specimens to evaluate the machine process employed for the 3D printing. A capability analysis is also conducted on the mechanical properties (obtained from the experimental tests) in order to calculate acceptable limits useful for possible structural analyses. The Young modulus, the proportional limit and the maximum strength here defined for PLA specimens allow to confirm the different behavior of FDM printed PLA material in tensile and compressive state. These differences and the calculated acceptable limits for the found mechanical properties must be considered when this technology will be employed for the design of small structural objects made of PLA, as in the present study, or ABS (Acrilonitrile Butadiene Stirene). From the statistical and capability analysis, the employed printing process appears as quite stable and replicable. These types of research together with other similar ones that will be conducted in the future will allow to use polymeric materials and the FDM technique to produce small structural elements and also to carry out the appropriate verifications.

“…The idea of this model is to build a neural network whose outputs are a degree of the input that belongs to each class [91][92][93]. The membership functions (MFs) of this model can be nonlinear, multidimensional and, thus, different to conventional fuzzy systems [94][95][96]. In ANFIS, neural networks are used to increase the efficiency of fuzzy systems.…”
