3D printed optics and light bulbs (w/video)

(Nanowerk News) Printed Optics is a new approach to creating custom optical elements for interactive devices using 3D printing. Printed Optics enable sensing, display, and illumination elements to be directly embedded in the body of an interactive device. Using these elements, unique display surfaces, novel illumination techniques, custom optical sensors, and robust embedded components can be digitally fabricated for rapid, high fidelity, customized interactive devices.

Light pipes inside the bulbs can direct light and create internal patterns.
Printed Optics is part of a long term vision for the production of interactive devices that are 3D printed in their entirety. Future devices will be fabricated on demand with user-specific form and functionality. Printed Optics explores the possibilities for this vision afforded by today’s 3D printing technology.
