“…In this figure, it was found that the layer thickness had the most important effect on the dynamic strength of printed CRFRC from a holistic point of view, followed by hatch spacing and strain rate.Specifically, printing parameters in this study such as layer thickness and hatch spacing could affect the microstructural characteristics such as fiber content and void content as discussed in Sections 3.1 and 3.2. It was well known that fiber content and void content have important influences on the mechanical properties of the 3Dprinted continuous fiber reinforced composites [11,38,47]. Comparing the results in Figure4with those in Figures5 and 7, it could be found that higher fiber content corresponded to higher dynamic strength whereas higher void content corresponded to lower dynamic strength.…”

3D-printed continuous natural fiber reinforced biocomposites have promising prospects due to their environmental friendliness and suitable mechanical properties. Understanding the dynamic mechanical properties of 3D-printed biocomposites is essential to expand their application. In this study, the continuous ramie fiber reinforced biocomposites (CRFRC) with different layer thicknesses and hatch spacings were fabricated via 3D printing technique with microstructure characterized. In addition, the dynamic strengths of 3D-printed CRFRC at four strain rates were investigated. The experimental results exhibited that the printing parameters presented nonlinear and interactive influences on the dynamic strength of CRFRC. Given this circumstance, machine learning methods were employed to link the dynamic strength of 3Dprinted CRFRC with different printing parameters. The experimental data were used to train, calibrate, and validate the machine learning models. The trained models were then utilized to predict the dynamic strength of CRFRC printed using different conditions. Behaviors under multiple strain rates were investigated over the whole parameter space. A good agreement was found between experimental results and predictions. Based on the prediction results, the relationships between parameters, microstructural characteristics and dynamic strength of printed CRFRC were quantitatively analyzed.

“…A series of studies have focused on the FDM 3D printing of natural fiber/PLA composites. The natural fibers involved include wood [ 4 , 5 ], flax [ 6 , 7 ], kenaf [ 8 ], ramie [ 9 ], jute [ 10 ], sugarcane bagasse [ 11 ], bamboo [ 12 ], rice straw [ 13 ], rice husk [ 4 ], energy grass [ 14 ], and so on. For FDM 3D printed natural fiber/PLA composite, its properties are decided to a great extent by the printing processes/parameters, thus the effect of the printing processes/parameters on the performance of FDM 3D printed specimen is currently being investigated by many researchers to promote the wider development of FDM [ 5 , 15 ].…”

In order to develop a new kind of filament material for the fused deposition modeling (FDM) 3D printing, the residue of Astragalus (ROA), one of the most important Chinese herbal medicines, and polylactic acid were chosen as the raw materials to FDM 3D print biomass composite specimens, the effects of the printing parameters on the properties of the specimens were investigated. The results indicated that the mechanical properties and thermal stability of the printed specimen were affected obviously by the parameters while the melting and crystallization behavior of the specimens were little affected. For the wettability, it was also little affected by the printing parameter except for the printing speed. Increasing the printing temperature and the filling density or reducing the printing speed and the layer thickness could improve both the mechanical properties and the thermal stability of the FDM 3D printed PLA/ROA composite specimen; reducing the deposition angle could also improve the mechanical properties while having little effect on the thermal stability of the specimen.

[16][17][18][19] It was proved that 3D printed composites reinforced by continuous fibers showed much higher mechanical properties than those reinforced by short fibers in previous studies. However, the bonding between deposited lines and between layers was still considered a weakness in 3D printed composites though composites were reinforced by continuous fibers.…”

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).
