1. A multi-beam resin curing method for whole-volume additive manufacturing of an object, comprising:
illuminating a spatial light modulator (SLM) with a light beam from a light source;
controlling the SLM to impress an image onto the light beam so as to produce a modulated light beam; and
using projection optics to produce at least two sub-image beams from the modulated light beam with each sub-image beam having a 2D intensity profile corresponding to a section of the image, and optically transporting the at least two sub-image beams independently of each other into a bath containing a photosensitive resin so as to project the 2D intensity profile of the at least two each sub-image beam to pass through a volume of the photosensitive resin so that the projected 2D intensity profiles transversely intersect each other in the volume of the photosensitive resin bath to form a 3D pattern which simultaneously cures select volumetric regions of the volume of the photosensitive resin and thereby forms the object.
