BAESFTLA, or Biaxially Extensible Scrolling-Folds and Telescopic-Lamellae Architecture, is an architecture for producing structures that can vary their length and width, often substantially, via a combination of scrolling-fold elongation and telescopic extension.

In its ultimate expression, BAESFTLA is composed of materials and electromechanical systems that are the products of mature molecular manufacturing, and the structure is capable of extending its surface area by three orders of magnitude.

The lamellae are joined to one another by sliding dado joints, and the telescopic motion is actuated by nanoscale electrostatic motors. The bulk material of the lamellae is typically composed of 3D woven graphene nano-ribbons. Sliding actuator-couplers (SACs) join the scrolling-fold layers to their neigbors.

Among the uses of this extensible material are stilt-legs, wing-packs and other forms of personal transport technology. This material is also used in the structure of limbs and other features of many robots and vecs, as well as for general construction purposes.

Like utility fog, extensible matter is sometimes used to create a temporary body for a remote operator, or to house a downloaded virtual sophont or upload. Since it is highly collapsible a user can carry a spare body in their pocket, to use as an extra physical presence where necessary (sometimes used as a decoy or additional soldier in combat situations, a messenger or as a social accessory.
