Additive manufacturing vertical stage for moving photocured material in a non-perpendicular direction from the image plane

An additive manufacturing system for creating an object from cured photocurable material based upon an object design, the additive manufacturing system comprising:

• an actinic radiation source, wherein the actinic radiation source selectively projects actinic radiation generally upwardly that corresponds to cross-sectional areas of the object design;
• a material tray having a bottom surface with a radiation transparent film containing the photocurable material, wherein the projected actinic radiation passes up through the radiation transparent film and defines an image plane along an x-,y-plane above the radiation transparent film within the photocurable material, the image plane defines a z-axis perpendicular to the x-, y-plane;
• a rail that defines a path that is not parallel to the z-axis;
• and
• a platform upon which the cured photocurable material object is supported above the radiation transparent film, the platform is constrained to move along the path defined by the rail.
