Hybridized light sources

Abstract:

The present disclosure generally relates to additive manufacturing of an object using both a digital light processing (DLP) projector and a focused energy source to irradiate a photopolymerizable material, and apparatuses and methods for the same. The DLP projector irradiates and cures an outer perimeter of the object, and the focused energy source irradiates and cures an inner region of the object. In a preferred embodiment, irradiation by both the DLP projector and the focused energy source occur from underneath a tank holding the photopolymerizable material and through a transparent window.
