“…Its high levels of strength, flexibility, and durability make it ideal for applications that call for durable parts, such as tools, working prototypes, or mechanical components. However, Mohd Radzuan et al 2023 [17] explained that using nylon in 3D printing with higher filler loadings can lead to issues such as delamination and poor adhesion. However, a post-drying process and optimized printing parameters can improve the mechanical properties, resulting in stronger samples.…”

“…Generally, PE products are processed via injection molding or 3D printing [ 20 , 21 ]. Compared with injection, 3D printing via fused deposition modeling (FDM) provides an opportunity to fabricate customized products on demand and has become more and more popular [ 22 , 23 , 24 , 25 , 26 , 27 ]. In FDM, PE fibers are extruded out of a tiny nozzle and undergo strong shearing, which is beneficial for orientational ordering and crystallization, and thus, contributes to the high tensile strength and Young’s modulus [ 28 ].…”

Polyethylene (PE), one of the most popular thermoplastic polymers, is widely used in various areas, such as materials engineering and biomedical engineering, due to its superior performance, while 3D printing via fused deposition modeling (FDM) provides a facile method of preparing PE products. To optimize the performance and assess the degradation of FDM-printed PE materials, we systematically investigate the influences of printing parameters, such as fiber diameter (stretching) and printer head temperature, and degradation, such as UV exposure and thermal degradation, on the mechanical performance of FDM-printed PE fibers. When FDM-printed PE fibers with a smaller diameter are prepared under a higher collecting speed, they undergo stronger stretching, and thus, show higher tensile strength and Young’s modulus values. Meanwhile, the tensile strength and Young’s modulus decrease as the printer head temperature increases, due to the lower viscosity, and thus, weaker shearing at high temperatures. However, degradation, such as UV exposure and thermal degradation, cause a decrease in all four mechanical properties, including tensile strength, Young’s modulus, tensile strain and toughness. These results will guide the optimization of FDM-printed PE materials and help to assess the durability of PE products against degradation for their practical application.

Fused deposition modeling (FDM) is one of the additive manufacturing (AM) techniques in which intricate shapes are produced effectively with time and cost. Thermoplastics and filler-incorporated thermoplastics composite materials were used in the form of filament. The mechanical properties of the printed sample varies with the parameters involved in FDM printing. In the present investigation, polyamide 6 (PA) with 20 wt.% of short carbon fiber (CF) was used as filament. The filaments were printed with different raster orientations namely 0°, 45°, 90°, and ±45° by keeping other printing parameters constant such as 100% infill density, 0.2 mm layer thickness, 30 mm/min printing speed, 240°C printing temperature, 80°C bed temperature, and XY or 0° body orientation with a clear justification studied. The printed samples were investigated for structure, morphology and mechanical properties using tensile test and impact test respectively. The results shows that bidirectional ±45° raster orientation specimens show the highest tensile strength of 35.2 MPa in comparison with 0°,45°, and 90° raster orientation, and PACF composite material showed improved mechanical properties as compared to pure PA. The highest impact energy was observed for a PACF composite with a raster orientation of 90°. Morphological analysis of composites showed a uniform dispersion of CF in PA matrix and improved interfacial adhesion between matrix and reinforcement.
