Method of producing a three-dimensional structure and fine three-dimensional structure
First Claim
1. A method of producing a three-dimensional structure, comprising the steps of:
- providing a needle-shaped nozzle body having a fine inside diameter at a tip thereof, the nozzle supplied with a fluid;
arranging a tip of the nozzle to be close to a substrate;
ejecting a fluid droplet having an ultra-fine diameter from the tip of the nozzle toward a surface of the substrate by applying a voltage having a prescribed waveform to the needle-shaped nozzle body via the electrode so as to make the droplet fly and land on the substrate, and thereby the droplet being dried to be a solidified substance after landing on the substrate; and
maintaining a position and continually ejecting subsequent droplets by applying the prescribed waveform voltage to the nozzle for the droplets being stacked on said solidified substance so as to form a grown three-dimensional structure,wherein the nozzle inside diameter is 0.01 μ
m to 8 μ
m,wherein an electric line of force is attracted to the top of the solidified substance of the droplet, and wherein the three-dimensional structure is grown by stacking the subsequent flying droplet guided along the electric line of force onto the top of the solidified substance,wherein a diameter of the ejected droplet is 15 μ
m or less, andwherein the fluid droplet dries and solidifies by evaporation and drying to increase the viscosity of the fluid to allow stacking.

Abstract
A method of producing a three-dimensional structure contains the steps of: arranging a substrate close to a tip of a needle-shaped fluid-ejection body having a fine diameter supplied with a solution, ejecting a fluid droplet having an ultra-fine diameter toward a surface of the substrate by applying a voltage having a prescribed waveform to the needle-shaped fluid-ejection body, making the droplet fly and land on the substrate, and solidifying the droplet after the fluid droplet is landed on the substrate; further a three-dimensional structure has a fine diameter comprises droplets having an ultra-fine particle diameter, wherein the structure is grown by solidifying the droplets and stacking the solidified droplets.
