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.
