of this paper we introduce the technology
that enables us to create Printed Optics and outline the fabrication
process and its capabilities. We then describe four
categories of fabrication techniques for Printed Optics: Light
Pipes, Internal Illumination, Sensing Mechanical Movement,
and Embedded Components. We conclude with discussion of
limitations and future research directions. With the continuing
emergence of 3D printing technology, we believe now is
an ideal time to explore the unique capabilities of 3D printed
optical elements for interactive devices.
