Advanced Engineering Materials, EarlyView.A multimaterial approach is introduced to improve upon auxetic structures by combining two different polymers into the same reentrant honeycomb structure via additive manufacturing. The deformation behavior as well as the resulting Poisson's ratio are thereby improved significantly.

Performance Comparison of Surface Sensitizers for Diode Laser Powder Bed Fusion of Polyamide 12
Advanced Engineering Materials, EarlyView.Laser‐generated nanoparticles transform standard PA12 powders into high‐performance, dye‐free feedstocks for diode laser 3D printing. Despite identical absorbance at 808 nm, CuS, LaB6, and CB coatings reveal striking differences in fusion and strength—unlocking new design space for recyclable, industrial‐grade polymers.

Dislocation‐Mediated Thermoelectric Performance and Mechanical Behavior
Advanced Engineering Materials, EarlyView.Dislocations can scatter phonons to reduce thermal conductivity, thereby enhance thermoelectric performance. However, dislocations also impact mechanical properties, leading to increased brittleness and altered plasticity. It is essential to clarify the complex relationship between dislocations, thermal transport, and mechanical stability to achieve a ...
