We present “Multi-Layered Inflatables, a novel multi-layered inflatable structure that enables the design and fabrication of complex, asymmetric 3D forms from stacked planar sheets. Our approach employs some thin sheets that are assembled with distinct bonding patterns to form three separate air chambers. Two outer pairs form the external surfaces, while the intermediate chamber serves as an internal layer that reinforces the structure against external forces. By controlling the bonding patterns and independently tuning the pressure in each chamber using a low-boiling-point liquid (e.g., Novec), we achieve localized in-plane contraction and expansion. This allows us to generate forms such as dome-and-flat hybrids or other non-uniform surfaces—configurations that were previously challenging to obtain with single-layer or conventional methods. Additionally, the internal chamber increases the overall stiffness by counteracting the deformation of the external surfaces.
