Additive manufacturing (AM) has several advantages that will make a revolution in polymeric material development. In the AM of polymeric materials, filament deposition modeling (FDM) has been widely used owing to its versatility, low cost, and efficacy. FDM includes different parameters and also an interlayer adhesion that contributes to the performance of the printed parts. In recent years, reinforcement has been introduced in FDM‐printed polymeric materials to improve performance. This review looked at different polymer materials that were printed using the FDM process. A systematic literature search was conducted on FDM‐printed polymers, and the mechanical and thermal performance of these materials was reviewed and critically reported. The performance of FDM printed polymeric materials has been discussed in relation to FDM process parameters, matrix type, fiber reinforcement type, particle reinforcement type, and lattice structure. In a nutshell, this review article will assist researchers working in the field of 3D printing of polymeric materials in understanding the various polymer and polymeric composites' properties and performance.

“…Both are important mechanical characteristics in designing LSs, providing an efficient technique for comparing the energy absorption capability of LSs with different masses. 10,12,32,33 Figure 10 shows the effect of strut angle variation on the specific load-displacement stiffness. It is clear that the SK goes up with increasing the strut angle, higher than 70.53 .…”

Lattice structures (LSs) have been exploited for wide range of applications including mechanical, thermal, and biomedical structures because of their unique attributes combining the light weight and high strength. The main goal of this research is to investigate the effect of strut length and orientation on the mechanical characteristics of modified body-centered cubic (BCC) LS subjected to a quasi-static axial compressive loading within linear elastic limit using finite element analysis. In this study, two sets of LS were built and analyzed in commercial finite element software, ABAQUS/CAE/EXPLICIT 6.16, using a “smart procedure,” which was developed for this research to reduce the computational time and increase the accuracy of results by creating hexahedral mesh elements. The first set comprises 13 models having fixed strut length with strut angle variation from 40° to 100° with a step of 5°. The second set also includes 13 models; however, having variant strut length, kept constant for a single unit cell and through the entire model but varied from one model to another, with the same strut angle variation as the first set. In addition, the BCC LS with a strut angle of 70.53° was replicated in both sets because it was considered as a reference model to compare the results with it. Furthermore, specimens of the reference model were fabricated by a fused deposition modeling- (FDM) based 3D printer using acrylonitrile butadiene styrene (ABS) material and tested experimentally under compression. Experimental results are observed to be in good agreement with those of the finite element simulation, hence the same loading and boundary conditions were adopted for all other models. It was observed that the fixed strut length BCC LS with a strut angle of 100° offers the highest modulus. However, the highest specific strain energy absorption and specific stiffness as well as the least value of weight were dictated by a variant strut length BCC LS with a strut angle of 40°.

“…Usually, researchers study the effect of changing the shape of the LCS such as changing length, diameter, and angle of the strut which forms a singular unit cell. 50–54 This gives a change in natural frequency and influence the vibration response as well as vibration bandgaps properties. Modeling can be introduced in various ways like LCS, composite structures, mass spring structure, and porous structure.…”

The adverse effect of mechanical vibration is inevitable and can be observed in machine components either on the long- or short-term of machine life-span based on the severity of oscillation. This in turn motivates researchers to find solutions to the vibration and its harmful influences through developing and creating isolation structures. The isolation is of high importance in reducing and controlling the high-amplitude vibration. Over the years, porous materials have been explored for vibration damping and isolation. Due to the closed feature and the non-uniformity in the structure, the porous materials fail to predict the vibration energy absorption and the associated oscillation behavior, as well as other the mechanical properties. However, the advent of additive manufacturing technology opens more avenues for developing structures with a unique combination of open, uniform, and periodically distributed unit cells. These structures are called metamaterials, which are very useful in the real-life applications since they exhibit good competence for attenuating the oscillation waves and controlling the vibration behavior, along with offering good mechanical properties. This study provides a review of the fundamentals of vibration with an emphasis on the isolation structures, like the porous materials (PM) and mechanical metamaterials, specifically periodic cellular structures (PCS) or lattice cellular structure (LCS). An overview, modeling, mechanical properties, and vibration methods of each material are discussed. In this regard, thorough explanation for damping enhancement using metamaterials is provided. Besides, the paper presents separate sections to shed the light on single and 3D bandgap structures. This study also highlights the advantage of metamaterials over the porous ones, thereby showing the future of using the metamaterials as isolators. In addition, theoretical works and other aspects of metamaterials are illustrated. To this end, remarks are explained and farther studies are proposed for researchers as future investigations in the vibration field to cover the weaknesses and gaps left in the literature.
