1. A form element for forming at least part of a formwork for a concrete part, comprising:
a plurality of flexible layers which are arranged one above the other in a planar manner, wherein the plurality of flexible layers have a first configuration and a second configuration;
wherein, in the first configuration, the form element is flexibly and reversibly and three-dimensionally deformed into a double-curved surface by movement of at least one layer of the plurality of flexible layers along its planar extent relative to an adjacent layer of the plurality of flexible layers; and
wherein, in the second configuration, the form element is stiffened and solidified in a deformed position by reversible connection of at least one layer of the plurality of flexible layers to an adjacent layer of the plurality of flexible layers which presses together adjacent layers and solidifies the form element.
