Abstract
A method of forming a three-dimensional structure using droplet-based freeform printing is provided. The method includes depositing a structural material through one or more nozzles onto a surface of a substrate by droplet-based freeform printing, such as inkjet printing, to form one or more three-dimensional structures including a smooth surface and one or more cross-sectional dimensions. The structural material undergoes a liquid-to-solid transition after deposition of the structural material, and the one or more cross-sectional dimensions are controlled by a droplet ejection frequency. A method of fabricating a matrix including a three-dimensional structure including forming a negative three-dimensional template using droplet-based freeform printing, depositing, such as casting, a matrix material over the negative three-dimensional template and at least a portion of the surface of the substrate and solidifying the matrix material to form a matrix including the one or more three-dimensional structures of the negative template is also provided.
