Direct Ink Writing of Recycled Composites with Complex Shapes: Process Parameters and Ink Optimization

Poisoning with writing ink.

Direct Ink Writing of 3D Functional Materials

New methods for materials fabrication at the microand nanoscale will drive scientific and technological advances in areas of materials science, chemistry, physics, and biology. The broad diversity of potentially relevant materials, length scales, and architectures underscores the need for flexible patterning approaches. One important example is the fabrication of 3D periodic structures comprise...

Hydrodynamics of writing with ink.

Writing with ink involves the supply of liquid from a pen onto a porous hydrophilic solid surface, paper. The resulting linewidth depends on the pen speed and the physicochemical properties of the ink and paper. Here we quantify the dynamics of this process using a combination of experiment and theory. Our experiments are carried out using a minimal pen, a long narrow tube that serves as a rese...

Restoration of Obliterated Ink Writing

High-Operating-Temperature Direct Ink Writing of Mesoscale Eutectic Architectures.

High-operating-temperature direct ink writing (HOT-DIW) of mesoscale architectures that are composed of eutectic silver chloride-potassium chloride. The molten ink undergoes directional solidification upon printing on a cold substrate. The lamellar spacing of the printed features can be varied between approximately 100 nm and 2 µm, enabling the manipulation of light in the visible and infrared ...
