Additive manufacturing is a promising fabrication method for optical components used for illumination tasks, as completely new design approaches are possible. In order to fulfill a certain illumination task the designer can develop any kind of 3D freeform optics or 3D shaped geometry within the optic design software. This design is sent directly to the additive manufacturing machine and printed out. After a rework of the optical relevant surfaces the optical component can be integrated into an illumination systems. Thereby an additional advantage of 3D printing is the combination of mechanical and optical subcomponents to one part in one printing run.
We will present our work on different design approaches and on the design rules for 3D printed light pipes used for specific illumination tasks. Additionally we will discuss the needed rework of the printed light pipes. Besides this we will go into detail on the propagation of light in light pipes build up out of two different printing materials, which enables us to go for a condensed light propagation. Finally we will show the results of a sensor based on light pipes, which allows the measurement of a tilt of a surface.
