1. A build platform for an additive fabrication device, the build platform comprising:
a rigid structure;
a mounting attachment attached to an upper side of the rigid structure and configured to removably attach and detach the build platform to and from the additive fabrication device;
a flexible layer, wherein in a first configuration of the build platform, the flexible layer conforms to a lower side of the rigid structure, and
one or more handles configured to be actuated to apply a force to the flexible layer, thereby producing a second configuration of the build platform in which at least part of the surface of the flexible layer is deformed away from the rigid structure.
