Abstract
Disclosed is a process whereby diverse classes of materials can be 3D printed and fully integrated into device components with active properties. An exemplary embodiment shows the seamless interweaving of five different materials, including (1) emissive semiconducting inorganic nanoparticles, (2) an elastomeric matrix, (3) organic polymers as charge transport layers, (4) solid and liquid metal leads, and (5) a UV-adhesive transparent substrate layer, demonstrating the integrated functionality of these materials. Further disclosed is a device for printing these fully integrated 3D devices.
