Abstract
An optical fabrication device includes a light source that emits light and cures a photo-curable resin, a digital micromirror device that reflects the light and projects a predetermined pattern, a microlens array disposed downstream of the digital micromirror device and that transmits the light that has been reflected by the digital micromirror device, an objective disposed downstream of the microlens array and that causes the light that has been transmitted through the microlens array to form an image, a container that holds the photo-curable resin, a sample platform disposed inside the container, and a controller that controls the digital micromirror device and causes the light to form an image having the predetermined pattern at each of levels that are different in distance from a main face of the sample platform.
