    摘要： The present application relates generally to photopolymer blends and related methods for use in an additive fabrication (e.g., 3-dimensional printing) device. According to some aspects, compositions are provided for the modification of a base photopolymer resin. The compositions may comprise colorant agent and/or cure-modifying composition. The compositions may be selected to cause, when combined with the base photopolymer resin to form a photo-curable composition, at least one property (e.g., color, depth of the cure) of the photo-curable composition to fall within a pre-determined range. Related kits and methods are also generally described.

    摘要： According to some aspects, a method of additive fabrication wherein a plurality of layers of material are formed on a build platform is provided. The method may comprise forming a layer of material in contact with a container, and subsequent to the forming of the layer of material, rotating the container relative to the build platform and moving the build platform relative to the container, thereby creating an effective fulcrum about an axis, wherein the rotating of the container and moving of the build platform causes the layer of material to separate from the container. According to some embodiments, the container may be configured to rotate about a fixed axis. According to some embodiments, moving the build platform may comprise moving the build platform toward the container.

    摘要： According to some aspects, an additive fabrication apparatus is provided configured to form layers of material on a build platform, each layer of material being formed so as to contact a supporting liquid or a film disposed within a container, in addition to the build platform, a liquid photopolymer, and/or a previously formed layer of a material. The additive fabrication apparatus may comprise a container and a leveling element, wherein the leveling element is configured to move across a liquid-liquid interface to promote or create a flat interface between the two liquids. According to some aspects, the additive fabrication comprises a film disposed between two liquids, wherein the film maintains or provides a flat surface at the interface of the two liquids.

    摘要： Substantially equal amounts of thermal energy may be provided over a build area of an additive fabrication device using as few as one heat source by selectively attenuating thermal energy emitted by the heat source. The thermal energy may be selectively attenuated by a structure that blocks portions of the thermal energy from being directly incident upon the build area such that the heat is normalized over the build area. The heat distribution over the build area may, in some embodiments, approximate the heat distribution produced by a flat field heating element, yet may be produced at comparatively lower cost and with less complex engineering.
