Abstract
According to some aspects, a method of additive fabrication is provided wherein a plurality of layers of material are formed on a surface of a build platform, each layer of material being formed so as to contact a container in addition to the surface of the build platform and/or a previously formed layer of material. The method comprises forming a layer of material in contact with the container and in contact with a previously formed layer of material, and subsequent to the forming of the layer of the material, separating the layer of material from the container by simultaneously applying a first force to the layer of the material in a direction perpendicular to the surface of the build platform, and a second force to the layer of the material in a direction parallel to the surface of the build platform.
