Abstract:
1. An inkjet printing method for forming a continuous three-dimensional structure, the inkjet printing method comprising: providing a substrate; forming a temporary structure on the substrate, wherein the temporary structure has a predetermined pattern for defining a filling groove on the substrate; performing a filling step for filling a plurality of ink droplets into the filling groove, wherein the ink droplets cover and contact with a surface of the temporary structure and a surface of the substrate at the same time, and a self-aligned effect is formed so that the ink droplets are self-aligned to fulfill the filling groove, wherein the self-aligned effect is a composition of a first surface tension between the ink droplets and the temporary structure, a second surface tension between the ink droplets and the substrate, and a gravity of the ink droplets; solidifying the ink droplets for transforming the ink droplets from liquid state into a solidified ink droplets structure; and removing the temporary structure, and leaving the solidified ink droplets structure, so that a continuous three-dimensional structure is formed; wherein a first contact angle and a second contact angle are produced under the self-aligned effect, the first contact angle is corresponded to a third surface tension on the temporary structure, and the second contact angle is corresponded to a fourth surface tension on the substrate, so that the ink droplets flow to the filling groove continuously.
