Abstract

Abstract: The stereophotolithography process allows a three-dimensional object to be built by layer-by-layer, space-resolved, light-induced polymerization of a liquid monomer into a solid polymer. The relationship between the light penetration depth in the photoreacting medium, the scanning speed of the laser beam on the surface of the resin and the laser power has been studied. Experimental measurements have been performed and compared with a kinetic model. Empirical laws of evolution of the polymerized depth vs. macroscopic parameters have also been determined allowing the optimal operating conditions in stereophotolithography to be defined.
