    摘要: A method and apparatus for eliminating or substantially reducing curling effects in stereolithographically formed objects. Synergistic stimulation is applied to a curable material to form a three dimensional object through the build up of successive layers. Curling between successive layers is eliminated or substantially reduced by curing a balancing layer in relation to a balanced layer such that reverse curl of the balanced layer caused by the balancing layer offsets or negates normal curl of the balanced layer caused by the balancing layer.
