In 2014, researchers from the Chinese Academy of Sciences (CAS), together with Tsinghua University researchers, published a paper in Science China Technological Sciences, which discussed how to more quickly and affordably 3D print using metal materials. The researchers postulated that unconventional methods, like liquid phase 3D printing, could potentially solve the issues. The two Chinese educational institutions didn't stop their work with 3D liquid metal printing there, but soldiered on, and recently published some brand-new research. The research paper presents a more "developed approach" of how the scientists were able to incorporate mechanical structures and liquid metals for functional electronics. Read more at
