Hybrid Additive Manufacturing of Highly Stretchable Bottlebrush Polymer Nanocomposites by Decoupled Extrusion and Photopatterning

Advanced Materials Technologies, EarlyView.
A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB
