Biomechanical Performance of Additively Manufactured Bone‐Mimicking Scaffolds with Graded Architectures

open access: yesAdvanced Materials Technologies, EarlyView.
Nozzle temperature of 180 °C suits well for supportless PLA stochastic scaffolds. The scaffolds exhibit higher strength and stiffness under sudden impact loading. Grading type shows significant influence on scaffold properties. Radial descending type performs best in both mechanical and permeability aspects. Graded stochastic scaffolds are suitable for

Electrolyte‐Jet 3D Printing of Copper‐Based Strain Sensors for Physiological Signal Monitoring and Robotic Manipulation

open access: yesAdvanced Materials Technologies, EarlyView.
Electrolyte‐jet (EJ) 3D printing turns copper ions into precisely arranged copper microspheres, which combine with flexible polymers and carbon nanomaterials to create durable, high‐sensitivity sensors. These sensors accurately monitor human motion and physiological signals. Real‐time robotic hand control via gesture mirroring demonstrates an intuitive

Additive Manufacturing of Negative Thermal Expansion Metamaterials Using Steels

open access: yesAdvanced Materials Technologies, EarlyView.
Architected lattices with tunable negative thermal expansion are fabricated from common steels using laser powder bed fusion metal additive manufacturing. Optimized multimaterial interfaces and geometry‐driven design produce robust, defect‐minimized structures that remain dimensionally stable up to 300 °C, enabling scalable solutions for thermal ...

Printability Metrics in Direct Ink Writing: Critical Review of the Literature and Novel Perspective Based on Dimensional Analysis

open access: yesAdvanced Materials Technologies, EarlyView.
The impossibility of defining universal printability criteria for Direct Ink Writing (DIW) requires “unpacking” the process into printing subfunctions. Each of these is rationalized by identifying dimensionless groups, allowing effective comparison between the various material‐ and process‐related parameters for printability purposes.

Advanced Emissivity Tuning Via Femtosecond Laser Surface Engineering

open access: yesAdvanced Optical Materials, EarlyView.
Femtosecond laser surface processing (FLSP) is employed to fabricate titanium‐based metamaterials with engineered micro/nano‐scale features that exhibit spectrally selective and omnidirectional thermal emissivity. By integrating advanced ellipsometry, electromagnetic modeling, and compositional analysis, the work reveals resonance‐driven emissivity ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
