System and method for three-dimensional printing

Abstract:

A method for preparing a three-dimensional object, in layers is described. The method may include forming a layer on a transparent substrate by selectively depositing liquid material on a transparent substrate based on image data of a cross section of the layer, the image data including at least a body region, wherein the material extends on the transparent tray outside a contour defining the body region; contacting the layer to a previously solidified layer attached to an elevated fabrication platform; and selectively curing the liquid material by irradiating the layer with curing radiation through the transparent substrate according to high-resolution image data of the cross section such that the material that extends outside the contour remains uncured.
