“…It is an extrusion-based method that employs thermoplastic material based on its hot-melt adhesive properties. [8][9][10][11] In the FDM process, the molten filament is deposited on the platform in a raster pattern to form the first layer. Subsequently, the desired product or part is completed by adding up successive layers onto the first layer.…”

The effect of printing angle on the mechanical behavior of 3D printed carbon fiber reinforced nylon composites is investigated. Three types of print angles, namely angular, vertical and horizontal, are considered in the present study. Dynamic mechanical analysis, and flexural and tensile tests are performed to evaluate the mechanical behavior of specimens. The dynamic mechanical analysis test reveals higher storage and loss modulus in horizontal specimens as compared with angular and vertical specimens, mainly credited with better mechanical restraints imposed by carbon fibers on the matrix movement. Higher damping capability was also noted with horizontal specimens. Flexural properties of horizontally printed specimens are better as compared with the other configurations attributed to good stress transferability between the constituents. Tensile specimens also depict higher modulus and strength for horizontally printed specimens owing to higher resistance offered by the carbon fibers to tensile loading and good compatibility of constituents. Finally, the structure–property relationships are understood by analyzing the specimens under a high‐resolution scanning microscope.

This paper investigated the effects of heat-treatment and loading directions on compressive properties of 3D printed continuous carbon fiber reinforced composites (CCFRC). After heat-treatment at different conditions, specimens with different stacking sequences were compressed under different loading directions. The effect of heat-treatment on the porosity and crystallinity of composites was investigated. The porosity of short carbon fiber reinforced composites decreased but that of CCFRC increased after heat-treatment at 200 C. The compressive properties of specimens were investigated in combination with changes in porosity and crystallinity. It was found that the compressive properties of composites usually increased with decreasing porosity induced by heattreatment. While the fiber direction was parallel to the applied loading direction, the yield strength of C-CCFRC and S-CCFRC increased from 208.1 to 281.6 MPa and from 218.5 to 264.4 MPa, respectively, though the porosity increased. After heat-treatment at 100 C for 4 h, the crack initiation of CCFRCs was delayed during compressive tests. Besides, heat-treatment could change failure modes of CCFRC after heat-treatment at 200 C for 4 h. More specifically, heat-treatment at 200 C for 4 h could result in delamination and a decrease in energy absorption of C-CCFRC (from 7.23 to 4.05 J).

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.
