1. A method comprising:
curing a photopolymer resin disposed between a first build surface and a flexible film layer to form a print layer of a printed part with the printed part at a first position, wherein the print layer of the printed part defines a second build surface attached to a first side of the flexible film layer facing the printed part, and wherein a second side of the flexible film layer opposite the printed part is attached to a surface of a substrate;
instructing the printed part to move in a direction transverse of the surface of the substrate to a second position while the substrate remains stationary, wherein instructing the printed part to move causes the flexible film layer to move with the printed part in the direction transverse of the surface of the substrate and detach from the substrate; and
with the printed part at the second position, translating a peeling mechanism between the second build surface and the flexible film layer to detach the flexible film layer from the second build surface.
