| Abstract Scope |
Three dimensional (3D) ceramic micro/mesoscale lattice structures are important for a wide range of technological applications. In spite of considerable progress in this area, the current processes suffer from control over dimensions at length scales below about a millimeter. In this research, we report an entirely new approach to synthesize complex 3D microengineered ceramic structures such as micro pillars and micro lattices by using Aerosol Jet (AJ) nanoprinting. Complex structures of zinc oxide with a minimum feature size of 30 um and having aspect ratios of up to 25:1 without any templating/support are demonstrated, thus filling an important gap in possible ceramic architectures. The structures show a shrinkage of 1-2% after sintering, leading to near-net-shape part fabrication. We demonstrate that the unique high surface-to-volume ratio property in ZnO nanoparticle assembled microlattice is highly beneficial for increasing the efficiency in water purification. |
