Novel Aqueous Conductive Ink for 3D Printing

Reference number: 7840

The field of high-temperature conducting ceramics is a nascent market with applications in membranes, thermal barrier layers,sensors and reversible fuel cells / electrolyser systems to name a few.

But present manufacturing methods have either proved to be too expensive and/or resulted in lack of reproducibility, geometry or weak material properties. Improvements in reproducibility and customisation can be achieved using 3D printing.

3D Inkjet printing is particularly suitable as it is non-destructive, has low material waste, is excellent at fabricating thin functional layers, and is compatible with manufacturing. However, the use of expensive organic solvent loaded inks has been problematic given the detrimental environmental and industrial impact. A team of academics from Imperial College have developed a cost-effective, aqueous-based, ionically and electronically conductive ceramic inks of yttria-stabilised zirconia (YSZ) capable of forming thin, crack-free, gas tight structures with reproducible geometries.
