All Inkjet-printed Organic Solar Cells on 3D Objects [PDF]

arXiv
Drop-on-demand inkjet printing is a promising and commercially relevant technology for producing organic electronic devices of arbitrary shape on a wide variety of different substrates. In this work we transfer the inkjet printing process of organic photovoltaic devices from 2D to 3D substrates, using a 5-axis robot system equipped with a multi nozzle ...

3D Conductive Polymer Printed Metasurface Antenna for Fresnel Focusing [PDF]

arXiv, 2018
We demonstrate a 3D printed holographic metasurface antenna for beam-focusing applications at 10 GHz within the X-band frequency regime. The metasurface antenna is printed using a dual-material 3D printer leveraging a biodegradable conductive polymer material (Electrifi) to print the conductive parts and polylactic acid (PLA) to print the dielectric ...

Geometry‐Assisted Phase Selection: Interplay of Phase Heterogeneity and Geometry in Gyroid Shell Metamaterials Printed with 17‐4 PH Stainless Steel

Advanced Engineering Materials, EarlyView.
This study explores geometry‐driven phase evolution in gyroid shell metamaterials made via laser powder bed fusion of 17‐4 precipitation hardened stainless steel. Locally hardened regions develop along the primary loading paths in the structure, which finite element analysis and geometric considerations link to enhanced gyroid strength.

On the Rigidity and Mechanical Behavior of Triply Periodic Minimal Surfaces‐Based Lattices: Insights from Extensive Experiments and Simulations

Advanced Engineering Materials, EarlyView.
This study examines the mechanical properties of triply periodic minimal surfaces (TPMS)‐based lattices, analyzing 36 architectures in elastic and plastic regimes. It evaluates the applicability of beam‐based scaling laws to TPMS lattices. Rigidity arises from the alignment of members with the load direction and solid regions preventing rotation.

SCS: Superior‐Vena‐Cava Compressing Shape‐Memory‐Alloy‐Based Implantable Device for Heart Failure

Advanced Engineering Materials, Volume 27, Issue 7, April 2025.
An implantable superior–vena‐cava compression device, utilizing biocompatible shape‐memory‐alloy actuators, regulates blood flow and thereby achieves an 18.6% reduction in end‐diastolic left ventricular volume in a porcine model of ADHF. This potential long‐term solution minimizes thrombosis risk by avoiding direct blood contact, offering a significant

Multiple‐Repeated Plasma Surface Treatments for Significantly Improving Bonding Performance of Metal‐Carbon‐Fiber‐Reinforced Thermoplastic Polymer Dissimilar Adhesive Joints

Advanced Engineering Materials, Volume 27, Issue 9, May 2025.
Multiple plasma surface treatments improved the Mode I fracture energy of metal‐carbon‐fiber‐reinforced thermoplastic polymer (CFRTP) joints by ≈240% compared to single treatments and nearly 2000% over untreated joints. This significant enhancement, achieved without modifying CFRTP surface roughness, is attributed to improved chemical bonding at the ...
