“…The result showed that the mechanical properties of UV-induced, chemically treated PLA improved significantly, compared to neat PLA, due to stronger cross-linking. Ming et al [ 20 ] used a UV-assisted FDM method with a dual-curing process for fabricating continuous fiber-reinforced thermosetting polymer composites (CFRTPCs). This research used UV irradiation to activate the photoinitiator and photosensitizer in order to precure the extruded material, and concluded that the combination of UV irradiation and post-heat treatment offers effective dual-cure solutions for 3D printing, and that it could be a reliable fabrication method for the development of thermosetting composite systems.…”

In order to optimize the efficiency of the Fused deposition modeling (FDM) process, this study used polylactic acid (PLA) material under different parameters (the printing angle and the raster angle) to fabricate specimens and to explore its tensile properties. The effect of the ultraviolet (UV) curing process on PLA materials was also investigated. The results showed that the printing and raster angles have a high impact on the tensile properties of PLA materials. The UV curing process enhanced the brittleness and reduced the elongation of PLA material. Different effects were observed on tensile strength and modulus of specimens printed with different parameters after UV curing. The above results will be a great help for researchers who are working to achieve sustainability of PLA materials and FDM technology.

“…[29] Considering the need for quick curing after the filament deposition, the widest resins used are those with an injection/cure temperature < 100 C with a short cure time. [30][31][32] Another usual factor in ensuring the impregnation quality is the viscosity, which influences the infusion parameters, void formation, and material geometry, and ensures an appropriate fiber/matrix interface. [13] Viscosity is directly proportional to temperature, in which the vibration of the molecules increases the monomers distance and decreases the shear stresses resistance.…”

High-performance fiber-reinforced thermoset composites processed by additive manufacturing (3D printing) are attracting substantial attention in both academic and industrial fields in a market currently dominated by thermoplastic matrices. Thermoset polymers have, nevertheless, several advantages over thermoplastic ones. This study aims at recommending suitable fibers and processing conditions that effectively improve the mechanical properties of thermoset composites produced by additive manufacturing. The influence of void content is also highlighted. A systematic review is performed here using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (P.R.I.S.M.A.) protocol as a guide aiming to identify the main findings recently studied. A total of 147 studies are initially identified within 2014-2020 using three scientific databases. Then, 29 articles are selected and described respecting several inclusion and exclusion criteria. The main findings are presented and discussed, and the gaps are identified to open up further investigations yet to be understood and exploited.

“…[27] However, the precise fabrication of parallel bionic microchannels in bulk materials for a large amount of water self-transport and evaporators with high-efficiency vapor generation limits mimicking transpiration. Recently, the fast development of additive manufacturing, commonly known as the 3D printing technique, [28] which has been widely applied in biomedical fields, [29] tissue engineering, [30] biosensors, [31] and so on, [32,33] has enabled us to mimic microchannels in plants with complex 3D microstructures. [34] Herein, we developed a new hydrogel based on the N-isopropylacrylamide monomer, which was fabricated by the projection microstereolithography (PμSL) based 3D printing technique.…”

Solar water evaporation, which can be utilized for seawater desalination and wastewater treatment, promises freshwater security with renewable energy. Herein, a bionic solar evaporator consisting of a hydrogel solar absorber and bionic microchannels fabricated by the projection microstereolithography based 3D printing technique is proposed. Such a bioinspired solar evaporator achieves a fast water self‐transport speed and a high solar water evaporation rate of 4.12 kg·m−2·h−1 under 1 sun irradiation (1 kW·m−2), and the solar thermal efficiency can be as high as 92.1%. However, both the evaporation rate and solar thermal efficiency are greatly affected by properties of the hydrogel, geometric parameters of microchannels, and intensity of the light source. Most significantly, the bionic solar evaporator is applied for wastewater treatment including the purification of organic dyes, acid and alkali, as well as metal ions. The purification rate can be as high as 99.999%, demonstrating amazing performance for clean water production. The bioinspired water evaporator promises applications for solar energy harvesting, photothermal conversion, as well as environmental engineering, such as solar vapor generation, thermophotovoltaic cell, sewage disposal, and desalination of seawater.
