Abstract Scope |
Three-Dimensional (3D) ceramic micro-structures are important for a variety of technological applications. In this project, we explored the challenges associated with effectively fabricating these ceramic micro-structures and sought to combat these challenges by using aerosol jet printing technology. Some of the challenges associated with manufacturing these precise micro-scaffolds is due to an inability to fabricate without sacrificial materials and with a low shrinkage percentage.With this technology, using a binder free ZnO nanoparticle ink, we were able to fabricate structures with feature sizes in the range of 30 micrometers using no supports with shrinkage of 2-5%. In addition, these structures show a significant increase in ductility when compared to bulk ceramics. This research broadens our ability to design and manufacture high-performance ceramic devices in multiple areas including biomolecule sensing, tissue regeneration, catalysis, and filtration. |
