3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics

Advanced Materials Technologies, Volume 11, Issue 15, 7 August 2026.
A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...

Investigating Three-Dimensional Auxetic Structural Responses to Impact Loading with the Generalized Interpolation Material Point Method

Buildings
Understanding three-dimensional (3D) auxetic structural responses to impact loading remains challenging due to large deformations involving failure evolution and the interaction between geometric and material instabilities. In this study, the Generalized

CrossMatAgent: AI‐Assisted Design of Manufacturable Metamaterial Patterns via Multi‐Agent Generative Framework

Advanced Intelligent Discovery, Volume 2, Issue 4, August 2026.
CrossMatAgent is a multi‐agent framework that combines large language models and diffusion‐based generative AI to automate metamaterial design. By coordinating task‐specific agents—such as describer, architect, and builder—it transforms user‐provided image prompts into high‐fidelity, printable lattice patterns.

Monitoring Auxetic Structure with FBG Sensor

e-Journal of Nondestructive Testing
Auxetic materials are a particular class of materials which present a negative Poisson ratio (NPR). This means that once they are stretched, they expand in the directions orthogonal to the applied load. The dual behaviour occurs during compression tests.

Auxetic structures in civil engineering applications: Experimental (by 3D printing) and numerical investigation of mechanical behavior

Results in Materials
Auxetic materials are a group of metamaterials that have a negative Poisson's ratio. The most important advantage of auxetics over conventional materials is higher energy absorption. Consequently, in Civil Engineering, a wide range of applications may be

Integrated Design and Process Optimization of FDM‐Fabricated Hexagonal Architected Thin‐Walled PA12 Tubes for Improved Compressive and Energy Absorption Performance

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
FDM‐fabricated PA12 thin‐walled tubes with five hexagonal architected designs (D1–D5) of increasing nodal connectivity were investigated to determine the effects of wall architecture, layer height, and print angle orientation on compressive performance, energy absorption, and dimensional accuracy.

The Viscoelastic Behaviour of Auxetic Metamaterials

physica status solidi (b), Volume 263, Issue 8, August 2026.
Stretch‐only auxetic unit‐cell viscoelastic models are extended from elastic honeycomb and keyway lattices using Maxwell and standard‐linear‐solid representations. Different horizontal and oblique relaxation responses make Poisson's ratio time‐ and frequency‐dependent, enabling tuneable auxetic behaviour for damping and adaptive structures.

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
