Humerus greater tuberosity (HGT) avulsion fracture is one of the most common types proximal humerus fractures. The presence motion and gap lead to failure implants, due force pulling from supraspinatus. In this work, electrospinning technology was applied fabricate PCL-PEG/CS/AST nanofiber with superior biocompatibility mechanical property. Furthermore, could promote proliferation osteogenic differentiation bone mesenchymal stem cells (BMSCs) in vitro. We believe that work indicates a promising way union HGT fractures by using nanofiber.

Abstract Sandwich structures are crucial in automotive, and construction industries due to their lightweight, high‐strength properties, insulation, energy absorption capabilities. In addition, 3D‐printed sandwich important customizable geometry controlled material distribution, which enhance strength stiffness. This study examines the mechanical properties of composite with a honeycomb core. The skin, fabricated using wet hand lay‐up method, consists glass, carbon, epoxy resin, while fused deposition modeling machine produces polylactic acid (PLA+) A full factorial design analysis variance were employed evaluate effects skin core orientation on through compression three‐point bending tests. performance improved core‐skin synergy, enhancing load distribution resistance. Carbon/epoxy skins offered stiffness strength, delaying failure modes, glass/epoxy provides flexibility cost‐efficiency. Hybrid combined these benefits, stability. vertical further maximized capacity minimized buckling compared horizontal alignment. Optical revealed crack propagation as primary mechanisms. Last but not least, finite element ABAQUS confirmed qualitative similarity load–displacement curves deformation behavior experimental results. Highlights Mechanical analyzed via experiment. Vertical improves compressive flexural over cores. deliver superior panels. Failure mechanisms include buckling, cell wall debonding, wrinkling/cracking. Finite results closely aligned tests, validating structural predictions.

Abstract Additive manufacturing (AM) of ceramics presents both exciting opportunities and significant challenges, particularly with the laser‐based AM processes. Ceramics are known for their special properties, such as high strength, corrosion resistance, temperature stability, but inherent brittleness processing demands make more complex. This review provides an updated overview most common techniques ceramics, including direct energy deposition, binder jetting, laminated object manufacturing, material extrusion‐based techniques. However, focus is placed on laser powder bed fusion (LPBF) a technique that has gained increasing attention its ability to fabricate complex ceramic parts enhanced quality. The delves into key causes critical defects commonly observed in LPBF, porosity, cracking, spattering, surface roughness. Recent advancements addressing these issues discussed, along limitations current defect prevention strategies. Furthermore, analysis mechanical properties LPBF‐fabricated giving insights how parameters influence performance LPBF‐printed parts. Modeling simulation also reviewed, highlighting role enhancing understanding behavior during LPBF. Overall, this highlights recent progress challenges techniques, while exploring future research opportunities, process optimization

The demand for lightweight, high energy-absorbing structures in engineering applications necessitates the development of advanced materials and manufacturing techniques. Composite sandwich structures, with their excellent strength-to-weight ratios energy dissipation properties, offer promising solutions. This study investigates absorption characteristics composite 3D-printed honeycomb core. skin was fabricated through hand lay-up techniques carbon glass fibers core from polylactic acid by fused deposition modeling. Quasi-static compression testing optical analysis evaluated ( E a ), specific SEA), crush force efficiency CFE). Sandwich vertical cores exhibited superior due to enhanced stability resistance buckling. Also, fiber skins achieved highest SEA values, demonstrating improved prior densification. Horizontal cores, despite lower SEA, provided stable crushing behavior, supporting consistent load distribution. Core plastic deformation identified as primary failure mechanism. results highlight significant influence structural orientation material selection on performance. vertically oriented fiber-reinforced showed greatest potential high-energy applications, offering cost-effective efficient solution needs.
