APPARATUS AND METHOD FOR FORMING THREE-DIMENSIONAL OBJECTS USING TWO-PHOTON ABSORPTION LINEAR SOLIDIFICATION

摘要

An apparatus and method for making a three-dimensional object from a solidifiable material using two photon absorption is described. The use of two photon absorption allows for the creation of a non-solidification zone beneath the exposed surface of a solidifiable material so that no separation is required between the most recently solidified layer of the object and a substrate such as a glass, a film, or a glass/film combination. In addition, when used with a linear scanning device, two photon absorption causes solidification to occur within a small spot area, which provides a means for creating larger, higher resolution objects than DLP systems or laser systems that use single photon absorption.
