This work was done during my time at MIT. I collaborated on a project that sought to find a new way to produce vibration damping metamaterials. This was accomplished by 3D printing (stereolithography) a rubber-like material with an internal fractal geometry. These fractals were filled with polyethylene glycol (PEG). The viscoelastic nature of this print configuration was able to successfully damp vibrations from one side of the print to the other. Additionally, the fractal geometries contained within the samples had central channels through which PEG could be added or removed. This variation in the quantity of liquid allowed for direct control/change of the damping properties of the prints.
