resulting in optics with compositional changes and geometric structures that aren’t possible to achieve with traditional manufacturing methods. As an example, their 3D printed gradient refractive index lenses could be polished flat to replace the expensive polishing techniques that are typically used for...

The 3D-printed film took 4 min to bend under UV light illumination (50 mW/cm2) (second panel in Figure 5a). Ceasing the illumination, a slight stress relaxation occurred in the film (third panel in Figure 5a). The stress relaxation was caused either by a temperature gradient of the ...
Imagine if it were possible to create 3D objects in the palm of your hand within seconds using only a single photonic chip. Although 3D printing has revolutionized the way we create in nearly every aspect of modern society, current 3D printers rely on la
