“…Comparisons were made by finding the deflections corresponding to a specified constant force value in the linear part of the load–displacement curve of each sample. In the study of Abouelmajd et al [ 73 ], they stated that the average error between the flexural strength values found between the experimental and FEA analysis was at the level of 5%. Gebrehiwot et al [ 74 ], on the other hand, stated that the average error between the numerical and experimental results of the deflection and strength values of PLA flexural samples produced by the FDM technique was below 10%.…”

In this study, the effects of the post-ultraviolet-curing process on the flexural, absorptive, and morphological properties of poly(lactic acid) specimens produced using a fused deposition modelling technique 3D printer were experimentally investigated. In this direction, 15, 30, 45, and 60 min post-UV-curing processes were applied to poly(lactic acid) three-point bending and absorption specimens produced at 190 and 200 °C. Three-point bending tests and morphological analyses were applied after the post-ultraviolet-curing process, and absorption tests were applied by immersing the post-ultraviolet-cured specimens in a distilled water bath for 1-, 3-day, and 1-, 2-, and 4-week exposure times. The changes in flexural strain properties for each experimental parameter were also simulated by the computer-aided finite element analysis and compared with the experimental results. It was observed that the post-ultraviolet-curing process increased the flexural strength of the poly(lactic acid) specimens produced at both 190 and 200 °C with the same increasing trend up to 30 min of exposure, and the most significant increase was determined in the specimens that were subjected to post-ultraviolet-curing for 30 min. Although the flexural strengths of the post-ultraviolet-cured specimens were higher than the non-cured specimens in all conditions, it was detected that they tended to decrease after 30 min.

The most important problem now is environmental pollution, which includes contamination of the air, water, and soil. In general, soil pollution harms the fields and renders them infertile, which is a serious worry. Agrowaste is one of the sources of soil pollution. Reusing this agricultural waste, specifically Natural fibers (NFs), by blending them with polymer-based materials to reinforce the polymer composite may be able to reduce the pollution caused by agro-waste. There are benefits and drawbacks to this strategy, though. As a result, from the perspective of mechanical characteristics, polymer composite materials made with NFs are subpar compared to polymer composites reinforced by, for example, carbon or glass fibers. Due to their renewable, biodegradable, and environmentally benign qualities, NFs can be extremely important in the textile and composites industries.In terms of both industrial applications and fundamental research, the natural fiber-reinforced polymer composite is expanding quickly. NFs are becoming more important as a result of environmental concerns due to their eco-friendliness. Since NF is a plentiful resource, the creation of NF composites will enable the replacement of current materials in a variety of applications. They are cheap, biodegradable, fully or partially recyclable, renewable, and renewable. Due to their low cost and low density as well as their good mechanical qualities, these composites are appealing due to the ease with which raw materials are accessible and renewable. Usually, continuous (very long) or discontinuous (chopped) NFs are utilized as reinforcement in composites. Given that NFs have superior mechanical qualities to synthetic fibers, there is growing interest in employing them to create high-performance technical products.

“…AM enables the production of complex tools, prototypes, and models offering the benefit of reasonable cost and short manufacturing time compared to the traditional methods such as machining and molding [1]. The ability to fabricate parts faster, cheaper, and without tooling increases the use of AM in medical sectors, functional prototype development, automobile fields, toolmaking, and many more [2][3][4][5]. Currently, AM technology has been developed to manufacture solid parts from a wide variety of materials including ceramics, thermoplastic polymers, and metals [6,7].…”

Fused deposition modeling (FDM) is one of the most used additive manufacturing processes in the current time. Predicting the impact of different 3D printing parameters on the quality of printed parts is one of the critical challenges facing researchers. The present paper aims to examine the effect of three FDM process parameters, namely deposition velocity, extrusion temperature, and raster orientation on the bending strength, stiffness, and deflection at break of polylactic acid (PLA) parts using Taguchi design of experiment technique. The results indicate that the temperature has the highest impact on the mechanical properties of PLA specimens followed by the velocity and the orientation. The optimum composition offering the best mechanical behavior was determined. The optimal predicted response was 159.78 N, 39.92 N/mm, and 12.55 mm for the bending strength, bending stiffness, and deflection at break, respectively. The R2 obtained from analysis of variance (ANOVA) showed good agreement between the experimental results and those predicted using a regression model.
