    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 根据一些方面，提供了一种在构建平台上形成多层材料的添加剂制造方法。 该方法可以包括形成与容器接触的材料层，并且在形成材料层之后，相对于构建平台旋转容器并相对于容器移动构建平台，从而创建关于 轴，其中容器的旋转和构建平台的移动导致材料层与容器分离。 根据一些实施例，容器可以被配置为围绕固定轴线旋转。 根据一些实施例，移动构建平台可以包括将构建平台移向容器。
