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.
