Abstract Additive Manufacturing, also known as 3D printing, has transformed conventional manufacturing by building objects layer by layer, with material extrusion or fused deposition modeling standing out as particularly popular. However, due to its manufacturing process and thermal nature, internal voids and pores are formed within the thermoplastic materials being fabricated, potentially leading to a decrease in mechanical properties. This paper discussed the effect of printing parameters on the porosity and the mechanical properties of the 3D printed polylactic acid (PLA) through micro-computed tomography (microCT), computational image analysis, and Charpy impact testing. The results for both… More >

Abstract Growing environmental concerns and the need for sustainable alternatives to synthetic materials have led to increased interest in bio-based composites. This study investigates the development and characterization of sustainable egg packaging waste (EPW) biocomposites derived from recycled wood fibers and fungal mycelium filaments as a natural binder. Three formulations were prepared using EPW as the primary substrate, with and without the addition of hemp shives and sawdust as co-substrates. The composites were evaluated for granulometry, density, mechanical strength, hygroscopic behavior, thermal conductivity, and fire performance using cone calorimetry. Biocomposites, composed exclusively of egg packaging waste,… More >

Abstract The growing environmental awareness, the search for alternatives to fossil resources, and the goal of achieving a circular economy have all contributed to the increasing valorization of biowaste to produce bio-based polymers and other high-value products. Among the various biowaste materials, lignin has gained significant attention due to its high aromatic carbon content, low cost, and abundance. Lignin is predominantly sourced as a byproduct from the paper industry, available in large quantities from hardwood and softwood, with variations in chemical structure and susceptibility to hydrolysis. This study focuses on softwood lignin obtained through the LignoForce™… More > Graphic Abstract

Abstract The use of additive manufacturing techniques in the development of unconventional materials can help reduce the environmental impact of traditional construction materials. In this paper, the properties of a 3D-printed biocomposite were evaluated. Biofilaments obtained by mixing pulverized bamboo fibers with polylactic acid (PLA) resin were extruded during the manufacturing process. To assess the effect of incorporating plant fibers, an analysis was conducted on the morphology, elemental chemical composition, crystallinity index, principal functional groups, thermal stability, surface roughness, microhardness, density, tensile strength, elastic modulus, and strain percentage of reinforced samples. The results were compared with… More >

Abstract Acrylonitrile–butadiene–styrene (ABS) is the main material used in fused deposition modeling (FDM), which has good toughness and strength, but the single ABS material has poor heat resistance, which tends to cause warping and deformation during the printing process. Polycarbonate (PC) exhibits good performance in heat resistance, allowing it to maintain stable performance at higher temperatures. In this work, PC was used as a blending modifier to prepare five kinds of ABS/PC composite filaments, and the mechanical and thermal properties of the ABS/PC (Acrylonitrile–butadiene–styrene/Polycarbonate) composite filaments were studied and analyzed. Results showed that the glass transition… More >

Abstract The intricate packing of elastic filaments, including cytoskeletal microtubules, actin filaments, and artificial nanotubes, is fundamental to understanding a plethora of cellular functions and their applications in cellular engineering. Through rigorous theoretical analysis, we investigate the packing dynamics of filaments within vesicles and explore the axial stretching of the vesicle–filament system. Our examination reveals how the interplay of stiffness and size ratios between filaments and vesicles drives transitions in vesicle configurations, prompting filament bending or coiling. We construct morphological phase diagrams to elucidate these transitional phenomena, highlighting the influence of pressurized vesicles in enhancing resistance More >

Abstract The aim of this study is to analyze the interfacial and the frictional properties of copper (Cu) reinforced polyethylene terephthalate (PET) filament. This Cu-Embedded PET filament will be used as an information transmitter. This filament was prepared by a co-extrusion process. Mechanical properties of these filaments have been quantified by tensile and pull-out analyses. It is shown that the mechanical properties of composite filament were improved by adding the copper filament (from 0.82 to 1.2 GPa). The results of the pull-out test revealed some adhesion between the copper and the PET despite the existence of More >

Abstract This article presents the results of experimental studies concerning the dynamic deformation and failure of a unidirectional carbon fiber reinforced plastic (T700/LY113) under compression. The test samples were manufactured through the filament winding of flat plates. To establish the strain rate dependencies of the strength and elastic modulus of the material, dynamic tests were carried out using a drop tower, the Split Hopkinson Pressure Bar method, and standard static tests. The samples were loaded both along and perpendicular to the direction of the reinforcing fiber. The applicability of the obtained samples for static and dynamic… More >

Abstract Much of our understanding of the events which underlie cell migration has been derived from studies of cells in tissue culture. One of the components that mediates this process is the dynamic actin-based microfilament system that can reorganize itself into so-called stress fibers that are considered essential components for cell motility. In contrast, relatively few studies have investigated cell movement along an extracellular matrix (ECM) which is known to influence both cellular organization and behavior. This opinion/viewpoint article briefly reviews cell migration during corneal endothelial wound repair along the tissue’s natural basement membrane, Descemet’s membrane. More >
