    Patent number: 11298874
    Abstract: A continuous additive fabrication system comprises a bath of photopolymer resin and a light source assembly having a light source and a motorized variable aperture. The light source assembly is operable to generate a focus point in the bath of photopolymer resin, the shape of the focus point at a curing plane within the bath of photopolymer resin corresponding to the shape of the motorized variable aperture. The continuous additive fabrication system further comprises a platform configured to support a build object and a drive mechanism (coupled to at least one of the platform and the light source assembly) configured to continuously move the curing plane through the bath of photopolymer resin. A size and/or shape of the motorized variable aperture is changed while the curing plane in continuously moved through the bath of photopolymer resin.
