Industrial Strategies and Solutions for 3D Printing: Applications and Optimization

Published Date

The challenges related to effective bonding, diminished strength, and mechanical performance of 3D models created through fused filament fabrication (FFF) remain significant focal points within the realm of 3D-printed structures. FFF, commonly known as 3D printing, is extensively utilized in crafting prototypes for various industries such as aerospace, medical, and automotive sectors. This technique involves feeding a thermoplastic polymer into a liquefier, which then extrudes a filament while traversing successive X–Y planes along the Z-axis direction. This process results in the gradual construction of a 3D component layer by layer. As the deposition advances, the heated filament is placed upon previously deposited filaments that are in the cooling phase. This action triggers their reheating, establishing a specific period during which the interfaces of contacting filaments achieve temperatures beyond the glass transition temperature (T g) for amorphous materials or the crystallization temperature (T c) for semicrystalline materials. This temperature range is essential for effective bonding to occur. Consequently, each filament must attain a sufficient level of heat during deposition, while avoiding excessive heat that might lead to deformation due to the force of gravity and the weight of subsequently deposited filaments in subsequent layers. Hence, numerous factors influence the quality of the produced component, such as the polymer’s temperature profile, and, consequently,

Fused filament fabrication (FFF), which is one of the additive manufacturing (AM) techniques, involves creating parts by depositing molten filament of a thermoplastic polymer, resulting from extrusion, onto a plate with precision. This process is controlled by a computer according to a previously recorded program. FFF includes the deposition of polymer filaments in successive x–y planes along the z direction, creating a layer-by-layer deposition mechanism. Among the wide range of available thermoplastics, only a limited number of polymers, such as polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS), as well as polypropylene (PP), are commonly used in this technology [1].One of the crucial limitations in the development of this technology is the challenge of achieving proper adhesion between the filaments and the layers, as well as preventing the formation of voids within the structure of the parts. This issue arises because the diffusion coefficient of molten thermoplastics, which exhibit very high viscosity, remains low. In the absence of external force or pressure, ensuring strong adhesion between each melted filament and the previously deposited neighboring filament–already solidified due to rapid cooling–poses a significant challenge [2-4]. During the transformation of polymers, several parameters can influence the performance of the final part. Notably, viscoelasticity (a combination

The design of 700‐bar composite tanks considering the safety factor imposes resistance to a bursting pressure greater than 1645 bars remains difficult which leads to the addition of carbon fibers. On the other hand, the specifications in terms of mass storage capacity and cost require the quantity of this same fiber to be limited. Thus, the optimal sizing of the composite remains one of the major challenges in the development of 700‐bar tanks. This study is focused on an optimum design of dome contours for 700 bar hydrogen tank type IV considering the geometrical limitations, winding condition, and the feasible direction. The study is centered on the composite part and is separated into two parts: a study of the manufacturing process (filament winding) in its fundamental aspects and a structural calculation under HyperWorks to check the mechanical strength of the composite layers and optimize their stacking and …

Fused filament fabricated (FFF) parts generally show anisotropic mechanical properties. Moreover, the anisotropy in FFF-printed parts varies with polymeric materials, depending on their characteristic relaxation and/or crystallization behavior. To acquire an in-depth understanding of the mechanical anisotropy induced by the FFF technique, polyphenylene sulfide (PPS) was chosen to investigate the effect of nozzle temperatures and nozzle speed on the mechanical properties of FFF-printed parts. In addition annealing of the samples at different times was chosen as a post-processing method to improve the mechanical properties. The optimized conditions through the highest value were selected by analyzing the Gray Relational Grade (GRG) values in the 16th trial using ANOVA and S/N investigation. It is found that increasing nozzle temperature gives rise to a decrease in crystallinity, slightly improving the tensile …

In Additive Manufacturing, wherein the construction of parts directly from 3D models is facilitated, a meticulous focus on enhancing the mechanical characteristics of these components becomes imperative. This study delves into the nuanced impact of the orientation of deposited layers on the mechanical properties of 3D printed Polylactic Acid (PLA) parts. Experimental testing, coupled with predictive modeling using Tsai–Hill and Tsai–Wu criteria, forms the crux of our investigation. The predicted ultimate strength from both criteria exhibits commendable agreement with the 3D printed specimens across a spectrum of orientation angles. Concurrently, Finite Element Simulations are meticulously executed to forecast mechanical behavior, taking into account the observed elasticity and plasticity in various orientations. Our observations reveal a significant augmentation in Young’s modulus and ductility/elongation—40% and 70%, respectively—when transitioning from θ = 0° to θ = 90°. Furthermore, the ultimate strength experiences a notable increase, leading to varied failure modes contingent upon θ. These findings underscore the pivotal role played by the orientation of printed layers in shaping the anisotropic behavior of 3D printed PLA parts, thereby integrating key process variables for optimization objectives. This study contributes valuable insights for professionals in the engineering, design, and manufacturing domains who seek to harness the advantages of 3D printing technology while ensuring that the mechanical integrity of 3D printed parts aligns with their functional requisites. It emphasizes the critical consideration of orientation as a design …

The thermocompression molding process allows composites to be made with longer fibers compared to injection molding and extrusion. However, during thermo-compression molding fiber-reinforced composites are exposed to complex effects, which can lead to specific fiber orientation/distribution and therefore affect the mechanical properties. The aim of this work is to study the effect of fiber orientation on the mechanical properties of the long-glass-fiber-reinforced polypropylene (GF50-PP) composite produced by the thermocompression process. Moreover, due to the application of this composite in cold liquid gas storage, it is interesting to study this effect under cryogenic conditions. In this study, composite plates of GF50-PP were cut to analyze the effect of fiber orientations: 0, 45, and 90 with respect to the Mold Flow Direction (MFD).

Despite the application of the Additive Manufacturing process and the ability of parts’ construction directly from a 3D model, particular attention should be taken into account to improve their mechanical characteristics. In this paper, we present the effect of individual process variables and the strain-rate sensitivity of Onyx (Nylon mixed with chopped carbon fiber) manufactured by Fused Filament Fabrication (FFF), using both experimental and simulation manners. The main objective of this paper is to present the effect of the selected printing parameters (print speed and platform temperature) and the sensitivity of the 3D-printed specimen to the strain rate during tensile behavior. A strong variation of tensile behavior for each set of conditions has been observed during the quasi-static tensile test. The variation of 40 °C in the platform temperature results in a 10% and 11% increase in Young’s modulus and tensile strength, and 8% decrease in the failure strain, respectively. The variation of 20 mm·s−1 in print speed results in a 14% increase in the tensile strength and 11% decrease in the failure strain. The individual effect of process variables is inevitable and affects the mechanical behavior of the 3D-printed composite, as observed from the SEM micrographs (ductile to brittle fracture). The best condition according to their tensile behavior was chosen to investigate the strain rate sensitivity of the printed specimens both experimentally and using Finite Element (FE) simulations. As observed, the strain rate clearly affects the failure mechanism and the predicted behavior using the FE simulation. Increase in the elongation speed from 1 mm·min−1 to 100 mm …

Sheet Molding compound (SMC) composites were subjected to water immersion tests in order to study their durability since such composites are of interest in automotive applications. Water sorption tests were conducted by immersing specimens in distilled water at 25-90°C for different time durations. In order to investigate the combined action of water and temperature over time on composite mechanical behavior, tensile tests and quasi-static loading were conducted. The mechanical properties of water immersed specimens were evaluated and compared alongside to dry composite behaviour. The tensile tests and quasi-static properties of the studied composite were found to decrease with the increase in moisture uptake. This decrease was attributed toinner structure dégradations by means of osmosis phenomenon. It was shown that hydrothermal aging affects mainly the fiber/matrix interfacial zone while a good …

Shape memory effect (SME) of polymers is a property that concerns both, macroscopic and microscopic changes. The variation of internal polymer properties such, as molecular weight (Mw), rigidity, and viscoelasticity could alter its SME. In this study, a bi‐parabolic model with six parameters is used to describe the viscoelastic behavior of a shape memory polymer (SMP) blend (40% poly(caprolactone), PCL/60% Styrene–Butadiene–Styrene) with different PCL Mw. These parameters are determined using the Cole–Cole method. Modeling curves (E″ = f (E′)) will be then compared to experimental data from dynamical mechanical analysis (DMA) tests. It is shown that the bi‐parabolic model predicts well the behavior of the SMP mixture for different Mw of PCL. Afterwards, the evolution of the model parameters with the Mw of PCL is investigated. It is revealed that, when Mw of PCL drops, the relaxation modulus E0 …

Influence of loading temperature on the damage mechanism of polyphenylene sulfide (PPS) reinforced by glass fiber (PPS/GF30) under tension was experimentally studied from quasi-static (QS) to high strain rates. Two kinds of PPS/GF30 samples were prepared: PPS-0° and PPS-90° (correspond to fibers oriented parallel and perpendicular to the injection direction, respectively). After microscopic observation and thermomechanical characterizations by dynamic mechanical analysis, tensile tests up to failure with strain rates varying from 10−3 s−1 to 100 s−1 have been carried out at 25°C and 120°C with regard to PPS/GF30 glass transition temperature. To achieve the coupling effect of high strain rate and high temperature, a special chamber was designed to install on the servo-hydraulic machine.

Bonding of parts produced by fused filament fabrication (FFF) significantly depends on the temperature profile of filaments depositing one top of each other. It is necessary to evaluate the temperature profile during fabrication of structures using both theoretical and experimental approaches. This work describes the overall heat transfer (using finite volume method) that exists in such a process by taking into account the possible phenomena that are developing during the manufacturing sequence: conduction between filaments, conduction between filament and support, and convection with the environment. Although the developed model is general and applicable to both amorphous and semi-crystalline polymers and/or composites, the recordings of temperature variation at the interface of adjacent filaments of a printed vertical wall of PLA illustrated good agreement by implementing very small K-type thermocouples …

The effect of molecular weight on the crystallization behavior of poly(lactic acid) (PLA) both isothermally and non‐isothermally was studied using differential scanning calorimetry and polarized optical microscopy. Two distinct crystal forms (α and α′) were investigated under normal conditions of crystallization for different molecular weights. Using microscopy, the growth rate of spherulites was measured and the nucleation rate was estimated. Heterogeneous nucleation and morphology with a variant α and α′ forms have been proposed. Spherulites from low molecular mass PLA contained more interlamellar amorphous phase. In addition, the results showed more rapid crystallization of α′ than the α form in isothermal conditions.
