Microscale 3D Printed Pillars and Porous Polymeric Structures: Manufacturability and Micromechanics

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates how two‐photon polymerization enables the fabrication of microscale solid and porous structures from IP‐Q, IP‐S, and IP‐PDMS resins. Combining morphological and mechanical characterization, the study provides the first systematic insights into IP‐Q mechanics and reveals how processing parameters affect structure and stiffness ...

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

open access: yesAdvanced Engineering Materials, EarlyView.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Large Area, Cost‐Effective, and Ultra‐Fast Fabrication of Mini‐Coils Toward Noninvasive Magnetic Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A simple, cleanroom‐free method produces flexible mini‐coils using automated blade cutting. The process is fast, low‐cost, and supports diverse materials. The coils show strong durability and performance under repeated bending. Demonstrated use in resistor‐inductor filters and magnetic nanoparticle control proves their adaptability.
