A group of engineers from Disney Research have crafted a new method to create interactive objects using 3D printers . Referred to as “printed optics,” the lure of this technology is the ability to transform inert 3D models into interactive subjects by embedding 3D printed light piping into an object with minimal electronic components. Illuminated by LEDs and mobile projectors, this new breakthrough in optics has the potential to replace LCD and LED screens to display information on smaller interactive devices.
