    Abstract: According to some aspects, a storage unit for storing a photopolymer resin is provided. The storage unit may comprise a photopolymer resin, a bottom face comprising at least one region of actinically transparent material, the actinically transparent material being actinically transparent with respect to the photopolymer resin, at least one wall extending upwards from said bottom face comprising at least one region of actinically opaque material, the actinically opaque material being actinically opaque with respect to the photopolymer resin, and a lid comprising the actinically opaque material and removably connectable to the at least one wall.

    Abstract: An improved additive fabrication device and a build platform are provided. The additive fabrication device is configured to form layers of material on a build surface. The additive fabrication device comprising: a build platform comprising: a rigid structure; an actuation structure attached to the rigid structure, wherein the actuation structure comprises one or more sheet handles and a flexible sheet, and wherein a first surface of the flexible sheet forms a build surface on which the additive fabrication device is configured to form layers of materials; and the one or more sheet handles are configured to be actuated to apply a force to the flexible sheet while at least a part of the actuation structure remains attached to the rigid structure, to deform at least a part of the flexible sheet away from the rigid structure.

    Abstract: According to some aspects, a method of additive fabrication wherein a plurality of layers of material are formed 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, actively bending the container around at least one fixed point such that the layer of material separates from the container. According to some aspects, an additive fabrication apparatus configured to form a plurality of layers of material is provided. The apparatus may comprise a container, a build platform, one or more force generators, and at least one controller configured to, subsequent to formation of a layer of material in contact with the container, actively bend the container around at least one fixed point via the one or more force generators, such that the layer of material separates from the container.
