TECHNIQUES FOR RELEASING PARTS IN ADDITIVE FABRICATION AND RELATED SYSTEMS AND METHODS

Abstract: an improved additive fabrication device and a build platform are provided. the additive fabrication device is configured to form layers of material on a build surface. the additive fabrication device comprising: a build platform comprising: a rigid structure; an actuation structure attached to the rigid structure, wherein the actuation structure comprises one or more sheet handles and a flexible sheet, and wherein a first surface of the flexible sheet forms a build surface on which the additive fabrication device is configured to form layers of materials; and the one or more sheet handles are configured to be actuated to apply a force to the flexible sheet while at least a part of the actuation structure remains attached to the rigid structure, to deform at least a part of the flexible sheet away from the rigid structure.
