Woven Eutectic Lamellar Structures Lead to Ultrahigh Strength and Energy Absorption Capacity in Additively Manufactured Lattice Structures

open access: yesSmall Structures, Volume 6, Issue 5, May 2025.
Herein, AlCoCrFeNi2.1 is selected to produce lattice structures by selective laser melting. The as‐printed lattice structures consist of numerous colonies of nanosized eutectic lamellar structures which are bent and interwind with each other to form a woven microstructure. The unique microstructure leads to unprecedented effective metal strength, yield

The effects of anodization and instrumentation on titanium abutment surface characteristics and biofilm formation

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To assess the impact of anodization and instrumentation on titanium abutment surface characteristics (surface roughness and wettability) and biofilm formation (viability and mass). Materials and Methods Titanium discs were obtained from pre‐milled abutment blanks made of titanium‐6aluminum‐7niobium alloy.

Nominal material density may not reflect TPS‐relevant density for 3D‐printed surgical reconstruction implants: An educational case study

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Additively manufactured (3D‐printed) surgical reconstruction implants are increasingly encountered in head and neck oncology and may introduce density assignment challenges during radiotherapy treatment planning. This case report describes a clinically significant dosimetric discrepancy arising from the application of nominal bulk material ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

open access: yesAdvanced Science, Volume 13, Issue 45, 13 August 2026.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Eradicating Brittleness of Ti-6Al-4V/Cu Dissimilar Brazed Joint using a Nb Diffusion Barrier [PDF]

open access: yesArchives of Metallurgy and Materials
Directly brazing titanium (Ti) alloy and copper (Cu) using silver (Ag) based filler alloy has been recognized to be of limited success owing to the embrittlement of intermetallic compounds (IMCs) presented at joint interface. In the current investigation,

Residual Al2O3 From Grit Blasted Components Operate as Third Body Wear Particles in Total Knee Arthroplasty: An Exploratory Study

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 8, August 2026.
ABSTRACT Despite the success of total knee arthroplasty (TKA), a small percentage of devices fail. Due to the high volume of surgeries performed each year, revision total knee arthroplasty surgery presents a burden on patients and surgeons. One aspect that may improve TKA outcomes is device design, specifically the use of grit blasting to increase the ...

Strength–Ductility Enhancement in Additively Manufactured Titanium Alloys via Neutral Element‐Mediated Microstructural Control

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT To overcome the challenges of the strength‐ductility trade‐off in laser additively manufactured (LAM) titanium alloys, and to avoid the intragranular microstructure degradation often caused by an exclusive focus on grain equiaxialization, this work proposes a novel strategy of “grain morphology‐intragranular microstructure co‐optimization ...

A Hybrid Compliant–Tendon Laparoscopic Instrument for Distal Articulation and Grasping: Design and Experimental Validation

open access: yesThe International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 4, August 2026.
ABSTRACT Background Conventional laparoscopic instruments provide limited dexterity in confined anatomical environments, whereas existing articulated designs rely on complex rigid joints or motorised actuation, increasing mechanical complexity and limiting miniaturisation.
