Abstract This research investigates the behavior of sandwich glued laminated bamboo (Glubam) structures with a core formed by biodegradable plastic fibers, specifically polylactic acid (PLA), fabricated using 3D printing technology. The influence of various fiber printing orientations (0° and 45/135°) on tensile and compressive properties was investigated. The experimental results indicated that polylactic acid with calcium carbonate (PLA+) printed unidirectionally and aligned with the loading direction (0°) exhibits superior tensile and compressive strengths compared to specimens printed bidirectionally at 45/135°. Furthermore, the effect of additives on bioplastics of carbon fiber (PLA-CF) and glass fiber (PLA-GF) additives… More > Graphic Abstract

Abstract Solid oxide fuel cells (SOFCs) have attracted considerable attention for their high efficiency, environmental advantages, and versatility in fuel sources. Research has shown that optimizing the structure of SOFCs can lead to significant performance improvements. Additive manufacturing (AM) has emerged as a promising technology for geometrical optimization of SOFCs, owing to its capability to create complex and programmable structures. However, fabricating three-dimensional electrode structures with fine, highly resolved features remains a significant challenge. Herein, a vat photopolymerization (VPP) 3D printing process was developed for fabricating the Nickel Oxide-Yttria Stabilized Zirconia (NiO-YSZ) anode structure of SOFC.… More >

Abstract Human tissues and organs exhibit not only intricate anatomical architectures but also spatially heterogeneous distributions of elastic modulus—for example, between cancellous and cortical bone, across the epidermis, dermis, and subcutaneous layers, and between healthy and fibrotic liver tissues. Conventional biomaterials often fail to replicate such mechanical heterogeneity, thereby limiting their capacity to recreate biomimetic physiological microenvironments essential for applications like tissue regeneration and disease modeling. Meta-biomaterials, artificially engineered through the rational structural design of continuous materials, have emerged as a promising class of materials owing to their highly tunable mechanical and biological properties. These attributes… More >

Abstract Complex hierarchical structure in nature with remarkable performances of such as lightweight, high stiffness and strength, and so on, has inspired researchers designing and fabricating aligned structures for reinforced composites. Conventional techniques like freeze-casting, self-assembly, wet-spinning, shear force, electric, and magnetic field have been demonstrated to achieve excellent reinforced structures. Still, they are limited to microstructure control and small-sized samples. While 3D printing techniques enable to achieve a large diversity of dimensions, multimaterial and multifunctional 3D structures. Particularly, recent 3D printing combined with external force e.g., shear force, magnetic and electrical field has been employed… More >

Abstract Biocomposites are one of the environmentally friendly materials as a substitute for synthetic plastics used for various applications in the automotive, household appliances industry, and interiors. In this study, biocomposites from Polylactic Acid (PLA) and sugarcane bagasse fibers (SBF) were made using the 3D Printing method. The effect of alkalization with NaOH of 0 (untreated), 4%, 6%, and 8% of the fibers were studied. The SBF in PLA was kept at 2% v/v from the total biocomposite. The characterization of all biocomposite tested using tensile, flexural, impact, scanning electron microscope (SEM), thermogravimetric analysis (TGA), and Fourier… More > Graphic Abstract

Abstract Please Creating mechanically robust tissue engineering scaffolds capable of delivering growth factors and stem cells in situ for hard tissue repair remains a significant challenge. Inspired by the spiral structure of ice cream, our group developed an advanced 3D printing technique known as cryogenic 3D printing to fabricate polyester-based scaffolds with embedded growth factors. This method utilizes water-in-oil (w/o) polyester emulsions containing growth factors as the printing ink, which is patterned onto a cryogenic substrate. The resulting scaffolds feature a hierarchically porous structure, allowing mesenchymal stem cells (MSCs) to easily attach and proliferate. Additionally, the… More >

Abstract Additive manufacturing (AM), a key technology in the evolution of Industry 4.0, has revolutionized production processes by enabling the precise, layer-by-layer fabrication of complex and customized components, enhancing efficiency and flexibility in smart manufacturing systems. However, one significant challenge hindering the acceptance of this technology is the limited print size, constrained by the machine’s small bed. To address this issue, a suitable polymer joining technique could be applied as a post-fabrication step.

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 >
