“…The static structural and explicit dynamic modules of ANSYS 2022 R1 were initially used to perform FEA simulations on the aforementioned specimens under both static and dynamic loading conditions. Boundary conditions were specified in accordance with the tensile, compression, and flexural analysis for the FEA models, which were created using a 0.5 mm mesh. , The equivalent Von Mises stress and total deformation under tensile circumstances were ascertained by performing static loading conditions on the respective ASTM specimens. Despite the fact that FEA has been used to assess the consistency between the mechanical behavior of experimental and simulation results, the latter is anticipated to evaluate the outcome under ideal circumstances.…”

The present investigation demonstrates the feasibility of dysprosium phosphate (DyPO4) as an efficient additive in polylactide (PLA) to develop 3D printed scaffolds through the material extrusion (MEX) principle for application in bone tissue engineering. Initially, uniform sized particles of DyPO4 with tetragonal crystal setting are obtained and subsequently blended with different concentrations of PLA to extrude in the form of filaments. A maximum of 20 wt % DyPO4 in PLA matrix has been successfully drawn to yield a defect free filament. The resultant filaments were 3D printed through material extrusion methodology. The structural and morphological analysis confirmed the successful reinforcement of DyPO4 throughout the PLA matrix in all of the 3D printed components. All of the PLA/DyPO4 composites exhibited magnetic resonance imaging and computed tomography contrasting properties, which were dependent on the dysprosium content in the PLA matrix. The detailed mechanical evaluation of the 3D printed PLA/DyPO4 composites ensured good strength accomplished by the reinforcement of 5 wt % DyPO4 in PLA matrix, beyond which a gradual decline in the strength is noticed. Representative volume elements models were developed to realize the intrinsic property of the PLA/DyPO4 composite, and finite element analysis under both static and dynamic loading conditions has been performed to account for the reliability of experimental results.

“…Moreover, the use of polylactic acid could cause pollution if there is no recycling, and the difference was the inclusion of thermal properties [14]. Further, numerical modeling was compared with experimental results for the mechanical properties [15]. Recent advances and capabilities of polylactic acid resulted in an environmentally friendly nature, glossiness, multicolor appearance, and ease of printing at an acceptable price [16].…”

With the advances in additive manufacturing, there is the idea of using 3D printers to produce spare parts in isolated systems such as ships, oceangoing vessels, warships, spacecraft, isolated stations, and so on. However, it raises the question of the reliability of such spare parts. One area that has not been explored much is the aging of electrical and dielectric properties, which could reveal weaknesses of 3D‐printed spare parts for use in electrical and automation systems. Therefore, the paper aims to investigate the change in resistance and dielectric constant. The results show that these changes could increase the probability of discharge and have serious consequences for electrical and automation systems.

“…However, numerical predictions of the mechanical behavior of natural fiber composites with polymer matrix produced by FFF technology are still in the early stages of research. Ezzaraa et al [ 22 ] conducted numerical and experimental analyses of 3D-printed samples made of a PLA-wood composite. The impact of the wood volume fraction and internal porosity on mechanical properties was investigated.…”

This article is focused on a mechanical properties investigation of three types of sustainable poly lactic acid materials manufactured using the fused filament fabrication process. The purpose of this work was to study the impact of printing strategies on the mechanical properties and predict mechanical behavior under tensile loading using finite element analysis. The testing of mechanical properties was conducted according to the ISO 527 standard. The numerical simulations were conducted in Simufact Forming 2022 software. Analysis of the experimental data showed a dependance of mechanical properties on the used printing strategy. The Clear PLA samples printed in the XY plane exhibited a 43% reduction in tensile strength and a 49% reduction in elongation compared to samples printed from the same material in YZ plane. The experimental results show the influence of the printing orientation on the mechanical properties of 3D-printed samples.
