Material scientists learn how to make 3D-printed liquid crystal shape-shift

Researchers show that by controlling the printing temperature of liquid crystal elastomer, or LCE, they can control the material's degree of stiffness and ability to contract - also known as degree of actuation. What's more, they are able to change the stiffness of different areas in the same material by exposing it to heat.
