Abstract: Metamaterial is a new field of research in engineered material which lately becomes object of interest due to its unique properties not found in natural objects. Properties such as bandgaps, wave guiding, cloaking and diffuser have been attractive research topics. In this paper, feasibility of using solvent-based extrusion freeforming is explored to print high density ceramic lattices for acoustic metamaterials application. An extrusion-based 3D printer was design and set up for low temperature printing of zirconia lattice structures. An experimental procedure was used to investigate the formation of bandgaps for the 3D printed woodpile sonic structures. This enables the transmission spectrum of the sonic structures to be obtained experimentally.
