Abstract: A method for producing a three-dimensional (3D) object on an additive fabrication device includes receiving, by a computer, print instructions for the 3D object. The print instructions include a sequence of print maps, each print map corresponding to a sub-instruction for producing a respective cross-section of the 3D object. The method also includes exposing, by an energy source, resin stored in a resin container at a print plane according to a first print map of the sequence of print maps, and modifying a second print map of the sequence of print maps. The method further includes exposing, by the energy source, resin stored in the resin container at the print plane according to the modified second print map.

Abstract: A curing system for an additive fabrication system includes a light source, a liquid crystal cell, and a first polarizer. The light source is configured to emit light at a wavelength suitable for curing a material. The liquid crystal cell is configured to receive the light from the light source. The first polarizer comprises a polyvinyl alcohol (PVA) matrix and organic dyes impregnated into the PVA matrix.

Abstract: A curing system includes a basin configured to receive a photopolymer resin, an ultraviolet light source, and a translating device. The ultraviolet light source is configured to selectively emit ultraviolet light. The ultraviolet light defines a pixelated array that illuminates at least a portion of the photopolymer resin. The pixelated array includes a first array axis and a second array axis oriented perpendicular to the first array axis. The translating device is configured to translate the pixelated array along a translation axis at an oblique angle relative to the first array axis.
