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...

Laser-assisted direct ink writing of planar and 3D metal architectures.

The ability to pattern planar and freestanding 3D metallic architectures at the microscale would enable myriad applications, including flexible electronics, displays, sensors, and electrically small antennas. A 3D printing method is introduced that combines direct ink writing with a focused laser that locally anneals printed metallic features "on-the-fly." To optimize the nozzle-to-laser separa...

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 ...

Direct Ink Writing of Three-Dimensional Ceramic Structures

The ability to pattern ceramic materials in three dimensions (3D) is critical for structural, functional, and biomedical applications. One facile approach is direct ink writing (DIW), in which 3D structures are built layer-by-layer through the deposition of colloidalor polymer-based inks. This approach allows one to design and rapidly fabricate ceramic materials in complex 3D shapes without the...
