Abstract: According to some aspects, a method is provided of forming a metallic object via additive fabrication, the method comprising obtaining a geometric description of a first object with an exterior surface, generating a geometric description of a second object, the second object bounded by the exterior surface of the first object and having one or more voids, fabricating said second object via additive fabrication based on said geometric description of the second object, and depositing a metallic material onto said second object, wherein the metallic material is deposited into said voids of second object.

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 comprises forming a raft structure in contact with the build platform, the raft structure formed from one or more layers of material and comprising at least one removal pocket adjacent to the build platform and forming additional material in contact with the raft structure. According to some aspects, an additive fabrication apparatus configured to form a plurality of layers of material on a build platform is provided. The apparatus comprises the build platform, and at least one controller configured to form a raft structure in contact with the build platform, the raft structure formed from one or more layers of material and comprising at least one removal pocket adjacent to the build platform, and form additional material in contact with the raft structure.
