Abstract: An active lattice capable of self-transforming responsive to a stimulus, such as heat or moisture, includes a plurality of links interconnected to each other at a plurality of nodes. At least a subset of links includes at least two materials that have different coefficients of expansion in response to an external stimulus. The two materials can be arranged in an alternating, periodic or aperiodic pattern. Embodiments can be used in apparel and sportswear, manufacturing, aviation and automotive applications, and furniture and interior products.

Abstract: A self-transforming structure is formed from a flexible, fibrous composite having a weave pattern of fibers woven at intersecting angles, the weave pattern having a boundary and one or more axes for the fibers, and an added material coupled to the flexible, fibrous composite to form a structure, wherein the flexible, fibrous composite and the added material have different expansion or contraction rates in response to an external stimulus to cause the structure to self-transform, and wherein the added material has a grain pattern oriented relative the weave pattern of the flexible, fibrous composite. Applications of the self-transforming structures include aviation, automotive, apparel/footwear, furniture, and building materials. One particular example is for providing adaptive control of fluid flow, such as in a jet engine air inlet.

Abstract: The combination of 3D printing technology plus the additional dimension of transformation over time of the printed object is referred to herein as 4D printing technology. Particular arrangements of the additive manufacturing material(s) used in the 3D printing process can create a printed 3D object that transforms over time from a first, printed shape to a second, predetermined shape.

Abstract: Described are methods for making three dimensional objects. A nozzle is positioned within a gel inside a container of gel. The position of the nozzle within the gel is changed while depositing solidifying material through the nozzle. The gel supports the solidifying material at the position at which the solidifying material is deposited. The solidifying material is solidified to form a solid material, which is a three-dimensional object.
