Researchers have developed a family of highly stretchable and UV curable (SUV) elastomers that can be stretched by up to 1100%, and are suitable for UV curing based 3-D printing techniques. Using high resolution 3-D printing with the SUV elastomer compositions enables the direct creation of complex 3-D lattices or hollow structures that exhibit extremely large deformation. Fabrication time for such SUV elastomers is also greatly reduced.
