Techniques for applying a peel operation during additive fabrication and related systems and methods

An additive fabrication device configured to form layers of material on a build platform, each layer of material being formed so as to contact a container in addition to the build platform and/or a previously formed layer of material, the additive fabrication device comprising:

• a build platform;
• a container arranged under the build platform;
• a plurality of mechanical linkages arranged under the container, each mechanical linkage of the plurality of mechanical linkages being coupled to the container and configured with joints at opposing ends of the mechanical linkage such that the mechanical linkage may rotate relative to the container;
• and
• at least one controller configured to, subsequent to formation of a layer of material in contact with the container, separate the layer of material from the container by causing motion of the container and at least some of the plurality of mechanical linkages.
