“…There are also problems created by the use of these materials such as sleeping of voids, poor adhesion between the fibers and the matrix, blocking of the printer due to the inclusion of filler, increased curing time, and modeling and simulation being made much more difficult. The works in the field try to solve these mentioned problems [ 44 , 45 , 46 , 47 ].…”

The paper aims to use Modern Dimensional Analysis (MDA) to study the polymers additive manufacturing optimization. The original part of the work is represented by the application of this nonconventional method in the field of polymers additive manufacturing. The laws of the model provide the complete sets of dimensionless variables, which cannot be offered by any of the classical methods (such as Geometric Analogy, Theory of Similarity, and Classical Dimensional Analysis). The validation of the method was performed experimentally. The original part of the work is represented by the application of this nonconventional method in the field of polymers additive manufacturing optimization. An application is presented and the necessary steps are analyzed one by one.

“…Most of these, however, focused on polymer-polymer blends [15,16]. It is important to pay attention to the blending of polymers and small molecules due to the following issues: Firstly, in industry, polymers have always been blended with small molecules to optimize processing conditions and enhance aspects of performance including flexibility, ductility, workability, and extensibility [17]. For instance, several kinds of plasticizers for nylon 66 (or nylon 6) were studied by Narkis and his co-workers [18].…”

Inclusion/Exclusion Behaviors of Small Molecules during Crystallization of Polymers in Miscible PLLA/TAIC Blend

et al. 2022

In this work, PLLA/TAIC has been taken as a model system to investigate the inclusion and exclusion of small molecules during the crystallization of polymers in their miscible blend. Our results indicate that it is the growth rate and diameter of PLLA spherulites that dominate the localization of TAIC. On the one hand, crystallization temperature plays an important role. Crystallization at higher temperature corresponds to higher growth rates and a greater diameter of PLLA spherulites. The former improves the ability of PLLA crystals to trap TAIC while the latter leads to a lower volume fraction of space among neighboring PLLA spherulites. The combination of the two contributes to the enhanced inclusion behaviors. On the other hand, when compared to melt crystallization, cold crystallization results in much smaller spherulites (from higher nucleation density) and sufficient space among spherulites, which accounts for the enrichment of TAIC in interspherulitic regions and for its enhanced exclusion. In the adopted polymer–small molecule blend, TAIC can enrich in interspherulitic regions even in its miscible blend with PLLA, which can be attributed to its stronger diffusion ability.

Additive manufacturing (AM or 3D printing) is known for large capacities like design freedom, reduced tooling, and production hours. AM evolving exciting advancements for new business models in different industries. Few research papers and studies are limited to material specifications, processes, or quality issues. So, this literature review combined with considerations of AM for polymers materials to quality process to get basic ideas or to lay the groundwork for future researchers. To outline the critical points for investigative queries and identify research gaps in this literature with primarily detailed info on innovation technologies. This review states polymers materials optimization and its manufacturing, all-purpose design considerations, and limitations define CAD source printing and step-by-step quality processes for the fortitude of the analysis to create previous research intended to advantage researchers for future business practices in Industrial revolution 4.0.
