Claim 0:
1. An additive fabrication device comprising:
a build platform with a build surface for forming an object thereon, wherein the build platform is configured to move in a vertical direction relative to the additive fabrication device;
a container for holding liquid photopolymer that is polymerizable on exposure to radiation, the container comprising:
an interior bottom surface;
sides connected to the interior bottom surface; and
a flexible display film extended between the sides of the container, wherein the flexible display film is configured to produce radiation to cure selected portions of the liquid photopolymer in the container, and

at least one controller configured to operate the flexible display film as a light source to produce said radiation from selected regions of the flexible display film to cure the selected portions of the liquid photopolymer and thereby form a layer of cured liquid photopolymer in contact with the interior bottom surface of the container and the build surface of the build platform and/or a previously formed layer of cured liquid photopolymer.
