Journal ArticleDOI
Designable dual-material auxetic metamaterials using three-dimensional printing
TL;DR: In this article, the effects of material selections and stiff material fraction on the Poisson's ratio, equivalent Young's Modulus, and maximum volume reduction were investigated, and the results from finite element analysis (FEA) and mechanical testing indicated that the auxeticity and mechanical properties of this dual-material auxetic metamaterial (DMAM) are distinctly different from those of traditional single-material AUAMs.
Journal ArticleDOI
Quantitative Prediction of Paravalvular Leak in Transcatheter Aortic Valve Replacement Based on Tissue-Mimicking 3D Printing
Zhen Qian,Kan Wang,Shizhen Liu,Xiao Zhou,Vivek Rajagopal,Christopher Meduri,James Kauten,Yung-Hang Chang,Changsheng Wu,Chuck Zhang,Ben Wang,Mani A. Vannan +11 more
TL;DR: A novel indicator of the post-TAVR annular strain unevenness, the annular bulge index, outperformed the other established variables and achieved a high level of accuracy in predicting post- TAVR PVL, in terms of its occurrence, severity, and location.
Journal ArticleDOI
Low-Loss 3-D Multilayer Transmission Lines and Interconnects Fabricated by Additive Manufacturing Technologies
TL;DR: In this paper, a low-loss 3-D transmission line and vertical interconnects fabricated by aerosol jet printing (AJP) is presented, which is an additive manufacturing technology.
Proceedings ArticleDOI
Aerosol jet printing for 3-D multilayer passive microwave circuitry
TL;DR: Aerosol jet printed 3D coplanar waveguides up to 50 GHz are demonstrated in this paper for the first time featuring a multilayer aerosol jet deposition process.
Journal ArticleDOI
Controlling the mechanical behavior of dual-material 3D printed meta-materials for patient-specific tissue-mimicking phantoms
Kan Wang,Yuanshuo Zhao,Yung-Hang Chang,Zhen Qian,Chuck Zhang,Ben Wang,Mani A. Vannan,Mao-Jiun J. Wang +7 more
TL;DR: In this paper, the mechanical behavior of soft tissues under a uniaxial tension is mimicked by dual-material 3D printed meta-materials with stiff micro-structured fibers embedded in a soft polymeric matrix.
