  • Patent number: 11130847
    Abstract: The present invention provides a 4D printed component that uses the photoisomerization stimulus as a method of activation. Other 4D printing methods use heat, moisture, a combination of heat and stress, and the heat from a light source as methods of activation. The present invention takes advantage of 3D printing capability and adds the capability of providing a printable material that dynamically changes shape over time when exposed to an external stimulus. The invention reduces the number of required 3D printed parts to create a moving object. This characteristic reduces the amount of onboard weight of the 3D printed components by reducing the number of parts required to create motion. The present invention removes the need for onboard sensors, processors, motors, power storage, etc. This characteristic will allow for manufacturing of, inter alia, novel medical devices, automated actuators, packaging, smart textiles, etc.
