Summary: A green and efficient dispersion method was developed to prepare cellulose nanofiber (CNF) reinforced polylactic acid (PLA) composites for fused deposition modeling (FDM) 3D printing. The addition of surface-modified CNFs enhanced the flowability and mechanical performance of the composites. The study has significant implications for improving the performance of 3D printing materials.

Summary: The widely used PLA in 3D printing poses challenges due to its mechanical weakness and water solubility, while the FDM approach offers cost-effective fabrication but with drawbacks in mechanical strength. Additives are crucial for enhancing the performance of FDM 3D-printed parts using PLA, leading to new developments in PLA composites.

Summary: 3D printing with polylactic acid (PLA) filament is shown to be a cheaper and more easily accessible alternative to resin printing for manufacturing PDMS molds. A method using chloroform vapor treatment is introduced to smoothen the printed PLA mold, which was successfully used to cast PDMS rings. The PDMS-glass well created with the PLA mold showed no leakage and was suitable for cell culturing, as tested with monocyte-derived dendritic cells (moDCs).

Summary: The aim of this study was to prepare a novel and biodegradable polylactic acid (PLA) film by incorporating polyolefin elastomer (POE), selenium nanoparticles (SeNPs), and triethyl citrate (TEC) as a plasticizer. The addition of SeNPs and POE resulted in a decrease in tensile strength and Young's modulus, while increasing the elongation at break of the nanocomposite films. The incorporation of SeNPs and POE also reduced the crystallinity and melting temperature of the PLA matrix, increased swelling, and improved water vapor permeability. The developed PLA/POE/SeNPs composite films exhibited enhanced barrier and mechanical properties, making them suitable for food packaging.

Summary: Additive manufacturing by 3D-FDM printing allows the production of patient-specific scaffolds for bone tissue regeneration. This study investigates the direct 3D printing of bone-related scaffolds using PLA and HA, and characterizes their properties. The results show efficient HA incorporation, uniform distribution, improved surface roughness, and higher bioavailability of the printed scaffolds. The scaffold porosity and mechanical properties can be controlled, and cell evaluation confirms enhanced cell proliferation.

Summary: Understanding the mechanical behavior and failure of 3D printed components is crucial for their application. Experimental studies have shown that the fracture in these materials depends on the printing parameters. This study aims to develop numerical models and perform experiments to investigate the constitutive behavior and fracture of 3D printed thermoplastics and composites.

Summary: The RGO-CIP composite microspheres were prepared using ethyl cellulose and epoxy resin. They effectively combined graphene (RGO) with carbonyl iron powder (CIP) to achieve multiple loss mechanisms and good electromagnetic absorption capability. The microspheres were used to prepare a 3D printed wire, which showed excellent electromagnetic properties. Heterogeneous interfaces formed on the surface and inside of the microspheres enhanced microwave reflections and scattering.

Summary: In this study, natural fiber-reinforced composite (NFRC) filaments for 3D printing were prepared using polylactic acid (PLA) reinforced with henequen flour. The experiments showed that the density, porosity, and crystallinity of the NFRCs increased with the flour content. The NFRCs exhibited lower Young's modulus compared to the printed PLA. At low flour content, the NFRCs showed improved tensile properties due to the reinforcement effect of henequen fibers. However, at high flour contents, the NFRCs exhibited decreased maximum stress, likely due to particle agglomeration and resulting defects.

Summary: This study explores the embedded 3D printing of silicone elastomer composites and examines the influence of the support bath on the physical properties of the composites. The results demonstrate that the liquid support medium enables a stable 3D printed structure and by tailoring the formula of the bath material, the extensibility and toughness of the elastomeric composites can be significantly improved.

Summary: This study investigates the effect of different plasticizers on the mechanical and thermal properties of 3D printed PLA-DDGS composites. It was found that the type and amount of plasticizer used significantly impact the morphology and mechanical properties of the composite materials. SEM micrographs showed phase separations and void formation in samples plasticized with glycerol and PEG, while DMA and FT-IR measurements confirmed the compatibility between PLA and ESO.

Summary: This study investigates the use of MoS2 as a modifier for PLA filaments in the FDM/FFF technique. It was found that the longitudinal filling pattern significantly increased the tensile strength by 49% and the addition of 0.5% MoS2 caused a significant increase of up to 457% in the wear indicator. Furthermore, the use of the additive improved processing properties, interlayer adhesion, and mechanical strength, resulting in improved print quality.
