  • Patent number: 11845229
    Abstract: According to some aspects, a method of additive fabrication is provided wherein a plurality of layers are formed on a build platform, each layer contacting a container in addition to the build platform and/or a previously formed layer, the method comprising calculating, using at least one processor, one or more forces to be applied to a first layer of the plurality of layers subsequent to the first layer being formed, said calculating being based at least in part on a determined area of at least one portion of the first layer that overhangs a second layer of the plurality of layers, forming the first layer, the first layer being in contact with the container and in contact with a previously formed layer of the plurality of layers, and separating the first layer from the container by applying the calculated one or more forces to the first layer.

  • Patent number: 10569526
    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.
