摘　　要：This study proposed a method for fabricating 3D microstructures of ice without a supporting material.The inkjet printing process was performed in a low humidity environment to precisely control the growth direction of the ice crystals.In the printing process,water droplets(volume=hundreds of picoliters)were deposited onto the previously formed ice structure,after which they immediately froze.Different 3D structures(maximum height=2000µm)could be formed by controlling the substrate temperature,ejection frequency and droplet size.The growth direction was dependent on the landing point of the droplet on the previously formed ice structure;thus,3D structures could be created with high degrees of freedom.
