Auxetic structures have been produced using 3D printing and knitted textile materials. A review of other auxetic textiles is presented along with the new materials. A range of configurations were developed, prototyped, and tested to demonstrate significant auxetic response, including Poisson’s ratio up to negative one. The concept of 4D textiles was employed to create environmentally responsive hinges in some structures, allowing the material to change shape in response to thermal stimulus.
