“…This innovative technology has been applied to the field of polymers and polymer-based composites. It includes various printing methods, such as fused filament fabrication (FFF) [3][4][5] or fused deposition modeling (FDM) [6][7][8], selective laser sintering (SLS) [9][10][11], stereo lithography appearance (SLA) [12,13], and electrospinning [14], enabling the realization of complex structures and diversifying the application of materials. Among these methods, FFF has been one of the most popular methods for manufacturing polymer and composite parts due to its advantages, such as cost-effectiveness, ease of maintenance, and reduced environmental impact [15,16].…”

The present work aimed to examine the tensile and flexural behaviors of biocomposites reinforced with continuous plant fibers, utilizing a range of polylactic acid (PLA) matrix materials and varying fiber content. These biocomposites were fabricated using an in situ-impregnated fused filament fabrication (FFF) technique. The study incorporated three different PLA matrix materials, namely PLA, PLA-Matte (PLA-Ma), and PLA-ST, each with distinct mechanical properties. The effect of different linear densities of continuous ramie yarns on the biocomposites was also investigated. The results show that adding continuous ramie yarn significantly enhances both the tensile and flexural strengths, as well as the modulus, of the matrixes. Furthermore, there was a positive correlation between the content of ramie yarn and the increases in strength and modulus. Moreover, the introduction of ramie yarns altered the fracture behavior of the biocomposites, shifting towards brittle fracture. This change significantly impacted the fracture toughness of the matrixes and resulted in a convergence of elongation at the point of breakage.

“…However, the fabrication approaches of bulk superhydrophobic materials often involve complex and time-consuming steps and are difficult to integrate into the printing of 3D superhydrophobic objects. So far, the successful cases regarding 3D printing of bulk superhydrophobic materials are limited to selective laser sintering (SLS) , and digital light processing (DLP). , Besides, these printed superhydrophobic materials are often brittle.…”

Although superhydrophobic surfaces have various promising applications, their fabrication methods are often limited to 2D plane surfaces that are vulnerable to abrasion and have limited adhesion to the substrate. Herein, an ultraviolet (UV) curable ink with bulk superhydrophobicity, consisting of poly-(dimethylsiloxane) (PDMS) resins, hydrophobic silica, and solvent (porogen), was successfully developed for UV-assisted direct write printing processing. After UV curing of the ink followed by solvent evaporation, the generated porous structure cooperates with silica particles to form a self-similar and hierarchical structure throughout the bulk material, which can keep its original morphology even after cyclic abrasion (over 1000 times) and thus exhibits durable superhydrophobicity. With this unique ink, UV-assisted direct write printing can not only create 2D superhydrophobic surfaces on various substrates (e.g., paper and wire mesh) but also fabricate self-supporting 3D superhydrophobic objects for various applications such as waterproofing and oil−water separation. The printed objects exhibited a stable superhydrophobicity against liquid corrosion and mechanical damage. In addition, the 3D printing approach can be used to optimize the oil−water separation performance of the superhydrophobic porous materials by tuning the pore size, thus presenting promising applications.
