High‐Pressure Homogenization: An Industrially Scalable Method for Producing PHBH Powders for Selective Laser Sintering

Advanced Materials Technologies, EarlyView.
This article investigates a sustainable approach to producing new powders for selective laser sintering by using high‐pressure homogenization to micronize biopolymers. The approach yields flowable, thermally stable particles with sub‐rounded morphology, enabling 3D printing of dense components with complex geometries.

Architected Elastomers as Load Bearing Actuators for Untethered Soft Robot Walking

Advanced Materials Technologies, EarlyView.
Electrically driven soft actuators that enable untethered soft robot walking are developed from 3D printed architected elastomers. The actuators have a handed shearing auxetic structure that enables fast, robust, and battery‐powered motions. The actuators are 3D printed from thermoplastic polyurethane on a desktop FDM printer.

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

Advanced 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
