Abstract
An apparatus and method for additive fabrication which helps to prevent the newly hardened layer from being separated from the previously formed layer of the object while the foil is peeled from the newly hardened layer is provided. In one embodiment, use of a peel angle helps prevent the newly hardened layer from being separated from the previously formed layer during peeling by distributing the peeling force so that less of the z-direction component of the peeling force is applied to the newly hardened layer. In another embodiment, the object can be oriented to initiate the peel at an area, of the object which results in a lesser initial peeling force applied to the newly hardened layer.
