BPNX1015: Ultra-Light Antennas via Charge Programmed Deposition Additive Manufacturing

Ju Young Park
2024

Multi-material printing employing charge-programmed material is utilized for phase array antenna fabrication, showcasing an ultra-lightweight RF phase array. Significant weight reduction is achieved through selective dielectric material printing. Our approach enables complex electronic device fabrication in one step, utilizing a mosaic of surface charge regions to deposit functional materials with precision. We demonstrate the inherently complex manufacturing process via homogeneous diffusion and fluid dynamics control.

BPNX1021: Realizing Three-Dimensional Alignment of Two-Dimensional Material for Isotropic Properties Enhancement via Embedded Direct Ink Writing (New Project)

Qiyi Chen
2024

The orientation of fibrous fillers, induced by shear forces during extrusion, has been demonstrated to significantly enhance mechanical properties, electrical/thermal conductivity, microwave attenuation etc., albeit primarily in a two-dimensional (2D) x-y plane. In this study, we present a novel approach for achieving fiber alignment in a three-dimensional (3D) context, with an emphasis on the Z-direction, by utilizing embedded 3D printing techniques. This process involves the extrusion and suspension of composite inks within a viscoelastic gel medium, during which the...

Charge-programmed 3D printing enables the fabrication of 3D electronics with lightweight and high precision via selective patterning of metals. This selective metal deposition is catalyzed by Pd nanoparticles that are specifically immobilized onto the charged surface and promises to fabricate a myriad of complex electronic devices with self-sensing, actuation, and structural elements assembled in a designed 3D layout. However, the achievable property space and the material-performance correlation of the charge-programmed printing remain unexplored. Herein, a series of photo-curable...
