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 ...

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 ...

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.
