An important characteristic of origami structures is rigid foldability. An origami tessellation is rigidly foldable if all sectors remain rigid and deflection only occurs at the crease lines. Because many materials used in engineering are much stiffer than paper, non-rigidly foldable tessellations (those that require deflection of the paper sectors) may have restricted movement when constructed out of these rigid materials. However, rigidly foldable tessellations may be constructed using stiff materials, leading to potential applications such as architecture and deployable arrays.
